The Ageless Mission
Hal Jordan/Green Lantern × Bruce Wayne/Batman
Timeline Information:
Both Bruce and Hal are already on their 50s, while had been married for 10+ years.
While on an intergalactic fight, an enemy blast hit Bruce that it made him fell to the ground. Having no clue to what happened to him when the other is saving him, he got asked multiple times how to finish the mission, but he couldn't recognize even as to why he was there in the first place.
But, the adrenaline of the fights keeps him awake for the time. Until it came down, the fight has been done for, and he told anyone that he didn't know them. Just right about when the people around him starts nagging at him, he's dropped unconscious.
They brought him to Alfred; a few of them helping Alfred to drop his armor, just to find out that it was younger Bruce Wayne that they are seeing.
There's no wrinkles on his face. There's no grey streaks on his temple.
As they're waiting for him to wake up, the Justice League (mostly Hal, because he has the power and the will to do it) searched for the information about the blast. Conclusively, that blast has made Bruce' appearance to be his younger self, while his memory is still intact but it would be hidden somewhere in his brain.
They have to confirm it when Bruce finally wakes up later.
Younger Bruce Wayne wake up, and— it really is not what they're expected the Bruce Wayne they know is supposed to be (maybe except for Oliver because he knew the man since they were younger).
He could only recognize Alfred and Oliver among the Justice League. He didn't recognize Dick and Jason (not to mention it also means he doesn't remember the Batfam).
But, also, maybe his memories has been mixed up; as to why he could recognize Clark and Diana later on. (And no, He didn't remember the Batman vs Superman thing, neither the making of Justice League and Steppenwolf).
Weeks passed, and they can do nothing about it, except if they found a way to undo it.
With Alfred and Tim's help, he manages to keep up with the updates about Wayne Enterprises. With Clark, J'onn, and Victor, he got helps to keep up with the Justice League. While also it feels confusing and awkward, Dick, Barbara, Tim and Cass helped him to keep up with the Batfam. While he got help from Oliver for a bit combination of all.
Younger Bruce... He could've managed to keep up with Younger Hal if they knew each other when they're younger.
Older Hal maybe not as "reckless" as he was used to, but it managed for Younger Bruce to "make a scene" about it. They have been called each other "names" for years, but the word Younger Bruce said, was kind of not expected by Older Hal.
Hal has tried to tone down his usual self (the usual self which he got when he's finally married to older Bruce) when he's with Younger Bruce. They could still manage to finish the missions. The only way to stop the unhealthy working space, is for older Hal to tone down his self; while also he would do anything by his own to finish the mission, he would choose not to debate on it if Younger Bruce says things about him.
It was actually Clark who actually helped him to recognize the closure of Hal and Bruce.
"There's no way. There's no way I've been married to that dude."
Clark doesn't responds to that. The least he would do is to make a spark on Bruce memory to remember that part of his life.
It was Diana, later on, to tell him that their "working space" hasn't been really healthy as his relation with Hal is not looking good by any chance. She knows that older Bruce is the wiseman of them all, she still feels that about the Younger Bruce; but she also thinks, younger Bruce has that spirit, but it maybe can't be the same as the older Bruce who has been with them for years, while younger Bruce was only with them for a few months.
He confronts J'onn to make him remember. But J'onn knew he couldn't. He couldn't get the access for Bruce memory as the blast has made it even harder to be breached into. The only thing he can do is light up a part of Bruce memory, that it can only be shown to Bruce while the mind readers couldn't see it.
Younger Bruce doesn't want to believe what he saw at first.
But, weeks after that, he asked Hal for a talk. Older Hal just stay silent when he doesn't say anything.
Younger!Bruce: "So, all this time... You knew?"
Older!Hal: "I don't know what you're referring to, but— I guess so."
Y!B: "Why... why didn't you tell me about it?"
O!H: "It could've been weird, isn't it? I don't even know if you're even gay at the first place to tell you that we— have been married for more than 10 years."
Y!B: "Why didn't you try?"
O!H: "Oh, I tried. Many times. I tried. But, You can't— for the love of God, You can't even take me serious. I know that it also my fault, but— what can I do about it? Should I yell to you about it? Should I ask all our team to tell you about it? Should I ask the Fam to scream it to you about it?"
Y!B: "Why did you stop?"
O!H: "I can only see that there's nothing I can do about it. It would be weird, awkward, uncomfortable on your part. You don't know how close we were truly are. I don't want to drag you on it. If I can't make you fall in love with me again, then I'll just keep it in my heart while hoping I would never loose you again to some enemy blast. I would be fine even though you don't know anything about us."
The debate goes on for the two of them. Where it goes to—
Y!B: "Then make me remember it! If we can't, make a new memory about it! I don't fucking care if it's going to rewrite my memory about it. I can no longer hold it, the pain I felt every time I wake up and you— suddenly appears on my memory. Make it stop!"
He doesn't tell the younger Bruce that he also feels the pain in his heart everytime he remember the memory of him with his older Bruce. He can't deny that this Bruce is his Bruce, but still...
O!H: "I can't rush you to it. I won't. I wouldn't do it if even you just told me to fuck off."
Punching some sense to Hal's face, it rages him for how fast it took Hal to gave up on them. Looking at Younger Bruce who's being furious, Hal recognizes the anger in Bruce's eyes. He looks at Bruce, hopefully. He took the Younger's hands into his, looking at the difference between their hands; between the younger hands and the older hands.
He brought younger Bruce's hands to his cheeks, to feel it. He closed his eyes and sighs in content. Relieved. He misses it. He misses Bruce. He misses their closeness.
It managed to make younger Bruce to shut up, and rather to take the quiet moment as an important thing. He caressed Hal's face gently, feeling the wrinkles that has started to appears more on his face. Feeling the relief.
O!H: "Before you think about it, I'm gonna be the one who took you on a date."
Y!B: "Starting slowly, aren't we?"
O!H: "Do you want it quick? I can do it quickly."
Y!B: "God damn you and your mouth."
O!H: "You liked it, though—”
Y!B: "What? What did you say??"
O!H: "Nothing! You'll find out soon enough, if you're game."
Y!B: "Did you just— challenge me?”
O!H: "Oh, boy... I did."
It took them another months to help Younger Bruce keep up with their "new memory". The Batfam, who already think of Hal as one of their responsible parent, managed to help Bruce to live up with it.
Sometimes, Bruce being younger and Hal being older makes them different than their usual both older Bruce and Hal. The "age" differences has made a new challenge for them.
