All the blame for this crack goes to @haveihitanerve and that Matt/Ben post
"So, you're telling me we are dating?"
"... Usually how it goes, yes."
"Oh, don't be a smartass..." Hal contemplates for a second, not lifting his eyes from the Bat as he moves around machinery. "Why would I even date you?"
Bruce slowly turns around. The cowl covers his lifted eyebrows, but knows Hal can feel them rising to the sky. "What do you mean?"
"No. I'm asking. Why would anybody not want to date me?" He half expected Hal to catch on the joke. He deflates at Hal's incredulous stare. A sigh "It was a-"
"HAH!" Hal barks. "How are you so full of yourself, Spooks?" And Hal is laughing. Bruce lets the air out of his lungs and turns to keep watching whatever it is on screen. "Who do you think you are? Bruce Wayne?" Hal is so busy laughing he doesn't notice the flinch, or the new input on the information about his memory loss.
"Why?" Curiosity wins. But he's still enough self aware not to turn around for the next question "Do you... Like Wayne?" He knows the recordings are going to hunt him every family meeting from now on.
Hal takes a second too long to answer. Bruce fears the answer.
The way his body relaxed to the answer surely needs to be studied. He'll note that down for another occasion.
"I don't like him" He blinks in surprise to his own voice.
"Of course you don't" This time, he does turn around.
"Exactly that. Of course big bad bat wouldn't like our Brucie." He bites down the smile forming "What's there not to like?" And Hal sighs.
He shakes the silly thoughts. "He's too fake"
"His persona. He's just too-"
"Oh, shut up! He's lovely!" No. Don't let the dissapointment slip. "Sure. He is obviously acting for the cameras," oh? "but you can't tell me the way he smiles and coos at his children is an act!" Oh... "That man is pure love!" Oh. Oh shit. "And when he hugs the people he does charities for?! COME ON!!" Oh shit, oh shit indeed. "He's just-" a long sigh. "Just."
Bruce takes a deep breath and sits on the cot's border. "Hal" he takes the man's hand, never missing how the man freezes on contact. Or maybe was his name. "Please don't panic"
He oh so slowly and carefully unclips the cowl from the back of his neck with one hand, never releasing Hal's from the other hand's grasp, and goes to pull his cowl forward. The movement has him looking down, so he lifts his head as he brushes his fingers through his messy sweaty hair.
Hal's eyes are comically wide. "Holy fuck"
"How the fuck did I score Bruce Wayne?"
"... Wait. Now you believe me?"
"Shut up! Wait no, don't dump me. Sorry. Holy shit. Oh my fucking god. How the FUCK did I-? OH MY GOD AM I DEAD?!"
"Dude, you can't just- fwoosh! Hi! I'm Bruce Wayne at me!"
Bruce sighs, endearment slipping through his smile. "You're so stupid. Now I understand why you reacted that way the first time"
"The first- We're really dating"
"Oh my god. I need to call Ollie" Hal covers his mouth "I'm dating Batman AND Bruce Wayne"
Bruce can only cackle at the man he had promised to marry.
