“Stop being so loud!” Tim hissed as him and Damian hopped into your sitting room window at two in the morning. “I thought you were meant to be the stealthy one.”
Cass slipped in behind them, her fingers to her lips. She was already moving further into your sitting room, with every intent to see her beloved sister, but did not want to interrupt your sleep.
“Shut up Drake.” Damian retorted. “Ukhti allows me into her apartment at any time. She won’t be mad at me. You, on the other hand-“
“I think she’ll be mad at all of us if we brake her stuff by acting like bulldogs.” Jason interrupted, sick of the brother’s bickering.
“Or maybe she’ll be mad because we’ll interrupt her ‘beauty sleep’” Dick grinned. “She takes that very seriously-“
“So do you Grayson. And heavens knows you definitely need it.”
“Hey!”
Tim opened his mouth to shush his brothers again, but was cut off by Jason’s voice coming from the kitchen.
“What. The. Fuck.”
Dick, Cass, Tim, and Damian looked at each other before walking to the kitchen, all of them stopping in the tracks when greeted by a sight they weren’t sure what to make of.
Wally West. Shirtless. Only wearing boxers. Standing in front of your open fridge, glass of water in hand.
Wally’s mouth was slight ajar, like he also couldn’t believe what he was seeing. Four out of the five people he feared the most just caught him red handed (the fifth was Bruce.)
There’s about ten seconds of a very terrifying and weird silence. Then it burst from three voices shouting at once.
Cass looked a mixture between stunned and slightly happy. One of Cass’ greatest skills is her ability to read body language, and she had observed you and Wally getting closer the past few weeks. She already had her unspoken suspicions, and was slightly pleased with herself.
Damian was immediately on the defensive. “How dare you dress like this in Ukhti’s home, West! You should have more respected for her and for yourself-“
Tim was asking questions that nobody gave him answers to. “When did this start? Was it right after her birthday gala? Because that means Bart was right. Does Bruce know? Does anybody know? How serious is this? A friends-with-benefits or a real relationship-“
Jason didn’t seem to believe what was in front of him, as if somehow convinced that you were on the unaware side. “Does she know that you’re standing practically naked in her kitchen? Why are you in her kitchen? Please say she was bandaging you up or something. Or that you needed food-“
But Wally wasn’t listening to them. He was staring at Dick, and Dick was staring right back at him. Neither of the two spoke. But Wally’s gut was already eating him.
He broke bro code. And he should’ve told Dick ages ago. But he kept pushing it off, because you always wanted to push it off. It wasn’t that you two didn’t want Dick to know, but it was sorta fun keeping the secret.
Well, it was a secret. Until Bruce found out a month ago.
You were in the medical room of the Tower, carefully wrapping your arm in a bandage after receiving a nasty slash from Poison Ivy’s thorns. Wally had joined you while you were half way through the act, wanting to make sure you were okay.
Wally was always more risky in public than you were. He trailed soft kisses up your arm, lingering on your neck, and then smiling against your cheek when you tutted at him.
“I’m trying to make sure I don’t bleed to death here Wally.” You snipped, but with no bite to your words. There never was when it came to Wally. He grinned back at you, his slender fingers going over yours as he helped you guide the bandage (you definitely did not need guidance, which to Wally, made the whole thing better as it had a better chance to annoy you.)
That lasted for a few seconds before a deep, unfortunately familiar voice came from behind.
“I’d appreciate it if you gave my daughter some space while she was recovering, Flash.”
Wally jumped about a foot in the air, leaping away from you as if you were burning hot as he turned around to look at his literally biggest fear.
“Yes, sir.” Wally got out immediately. “I was just- just seeing how . . . how she was doing after the-“
You rolled your eyes. “He was only checking on me, Batman.” You didn’t know how much Bruce had gathered, but reaction can tell him everything. It was pointless anyway, Wally had given him enough reaction to figure every detail out.
Bruce hummed, his cape still tucked around his shoulders to look more intimidating towards the young male.
“I’d like it if my daughter was more honest with me.”
You paused, looking at your dad. Wally stared you, making it clear that he’d follow whatever story you pulled. But you just sighed, and shrugged. You were too tired to lie anymore. Plus, you could tell from Bruce’s face that he already had you and Wally figured out.
“I’m sorry we hid it from you.” Wally blinked at your words. He’ll always find the silent conversations you and your father have very unsettling.
“How long have you known?”
“I’ve been suspecting for about two weeks now.”
You raised your eyebrows. “And you’ve only just come to us now? That’s surprising for you.”
Bruce was quiet for a moment, and then decided to make you feel a bit more guilty. “I was waiting for you to come to me.”
You pursed your lips. “I was going too. I just . . .” You looked at Wally. “We wanted to keep to ourselves. Just for a bit.”
Bruce nodded.
And then, after Wally got threatened (only a little) by Bruce, which he did expect, the awkwardness sort of disappeared. Because Bruce wanted to perform a little experiment of seeing how long it would take your siblings to catch on.
So then you and Wally’s constant unspoken fear of being caught vanished, and it turned more into a game. It was like pushing a limit to see how much your siblings would simply not notice or look past.
You and Wally had to dodge Damian the most, as the boy had a silent preference for you, especially when it came to missions. Damian liked being paired with his older sister for patrol or mission because you and his techniques worked well with each other, and you two often had the same line of thinking.
So it would happen a couple of times where Damian would go searching for you, only to walk into the meeting room to see you and Wally standing very close together. And for a second he thought he heard you giggling.
Damian cleared his throat to announce his presence. “Ukhti. It’s patrol time together.”
You and Wally sprung up, taking a step or two away from each other. You nodded quickly, swallowing your smile down.
“Let’s go, then.” You let Damian go in front of you, taking the chance to glance at Wally to give him a small wave.
Later on a rooftop, Damian spoke. “What were you and West doing?”
You hummed. “Just looking at the vent plan of a warehouse where a suspected drug dealer operates. Might be big bust, so Flash and I are studying the case.”
Damian nodded, satisfied with your words.
You were surprised you manage to dodge Tim as long as you did. The closest he got was when he caught you in the Batcave at 7 am in your pyjamas. You were hunched over the Batcomputer, watching the security footage of the camera placed outside your bedroom wall. He watched you for three seconds before speaking, making you whip your head back at him.
“What are you doing?”
“Nothing.” You said, a second too early. “Just thought I heard something last night. Wanted to double check.”
Not completely unusual. Tim narrowed his eyes before just nodding.
“Alright.”
When you left, he watched the last couple of hours from that camera himself, but didn’t see anything noticeable.
Little did Tim know you spent the last hour wiping the footage of Wally scaling your wall last night, and making sure that the footage matched up to the last second so that you wouldn’t be caught.
Cass was the hardest to lie to or avoid. She was so perceptive, and you could never fully tell how much she knew or what she didn’t know. Plus, she might be the one you were feeling the second most guilty about lying to her.
You and Cass are close. She’s your only sister, and you hers. You two often sleep in each other’s rooms when one of you finds it difficult to drift off for various reasons. And sometimes during these sleepovers you end up whispering into the darkness to each other. Secrets you wouldn’t trust with anyone else.
You don’t like lying to Cass about anything, and she’s the hardest to lie to. She can tell straight away by your body language if you’re hiding something, and she knew you were.
She could feel how your shoulders relaxed when Wally was mentioned, but tensed right back up again if she asked what you thought of him. She could see the slight clenching of your jaw when you tried to appear casual, claiming you “never gave him much thought. He’s just one of Dick’s friends.”
And now each one of them are realising that all those little lies you told, the situations you carefully avoided, all lead back to the ginger man standing in your kitchen half-naked.
As silence fell upon the group again and the voices were replaced with wide-eyed stared at each other, the weird atmosphere was interrupted by someone else moving.
Your footsteps were heard from the hall, your slippers softly slapping against the wood before you entered the kitchen, rubbing at your eyes.
“Wally? You said you were grabbing a snack ten minutes ago. I thought you were supposed to be the fast-“ But you stopped short when you saw your siblings packed together on one side, and your secret boyfriend on the other side.
And then the chaos started again, just now with your voice added in.
“Why didn’t you tell us?”
“Because I don’t have to disclose every detail with my siblings! I can have my own life for once.”
“Out of all the people you go for-“
“Hey!” That one was Wally, the first word he’s spoken this whole time.
After few more shouts, a particularly loud one echoed through the room. A voice who could silence the room with one command because he was a natural born leader, and an inspiration to everyone currently in the room. “Stop it. All of you.”
Dick Grayson. The only one who hasn’t spoken yet, but it looked like everyone was just remembering that he was there too, and that his opinion could really make or break the whole thing.
You and Wally exchanged a glance out of pure habit and familiarity when you noticed Dick, and it was that move that made him pause.
When presented with an unknown situation, you had looked towards Wally. And Wally had done the same. His two best friends had found their own language with each other that didn’t need to be spoken to be heard. Dick blinked, and looked towards his four younger siblings beside him.
Damian opened his light to protest against Dick unspoken command, but Dick stopped him with a look. He huffed before following Cass out of the kitchen, presumably going back outside to go home after opening their can of worms.
“Dick, we-“ You started.
“How long?” His words were simple, and you couldn’t gauge if he was happy or furious. But you didn’t hesitate.
You tsked. “That’s your first question?”
Dick’s eyes darted between the two of you, and you really thought you were about to fight this guy. Until his face broke out in a smile.
“Thank God!” He exclaimed, his arms laughing over both of you. “I was getting sick of the heart eyes you two were making at each other. So who manned up and said it first?”
Wally blinked. “You aren’t mad?”
Dick laughed. “Why would I be mad?”
You scoffed. “Maybe because you’ve gotten so weird over any boy that interacts with me, claiming that you need to threaten their collarbones.”
“That’s completely different.” Dick said, like it was obvious. “Those were guys I didn’t know. But of course I trust you, Walls. You’re my best bro.” His smile faltered. “But yeah, if you do hurt my sister, I will break your
collarbones.”
“Noted.” Wally muttered, but grinned back at his friend. You rolled your eyes beside them.
A few minutes later, Dick was crawling back out your living room window.
“Please just text me next time you decide to bring the whole family into my apartment.” You chided, before disappearing back into your bedroom.
Dick turned to Wally. “She’s your drama queen to deal with now, I guess.”
Wally smiled, “wouldn’t want it any other way.”
Dick nodded. “Happy for you man. I wish we could’ve had this conversation with you wearing some more clothes, but I guessed it worked out.”
“Thanks man.”
And with that, Dick joined his siblings in the batmobile to drop them off to the Cave before returning to his own girlfriend.
Wally crawled underneath the covers, sliding his body around yours where you were already texting Bruce.
You: They just figured it out. Three weeks and nine days. Not too bad.
Bruce: Noted. Thank you for indulging my experiment.
You: No problem. It was quite funny.
Wally watched your face as you stared at Bruce’s next messages for quite some time.
Bruce: Agreed. You should sleep now. Extend my good night wishes to West.
Bruce: I love you.
You put your phone away on your nightstand before curling into Wally. There was a minute of silence before:
“I really thought Dick was going to scalp me for a second back there.”
You hummed before mumbling, “I wouldn’t lower my guard around him.”
Wally didn’t get a chance to question your words before he heard your slow and steady breathing next to him, your thoughts safe and relaxed after the event of the evening.
Wally couldn’t say the same.
