Y/N was now in a boat outside whistling very bored as he sighs and shows an old stolen phone and starts to play Candy Crush.

Y/N: Heh... classic.

Inside the boat, Talia with a dress was serving two drinks with Batman behind him.

Talia: Would you like a drink?

Batman: Last time, that didn't go so well.

Talia: Oh you're right. *putting the bottle of wine down and walks towards him* If I remember correctly I put a little something in your beverage.

Batman: *as Talia leaned towards him and also looking at him* Same way I remember it.

Talia: *caressing his chest* It made you romantic.

Batman: It made me do what you wanted.

Talia: *looking at him again* Was it all bad beloved?

Talia puts a leg by his but Batman doesn't even flinch, not even a single muscle movement and also she was hugging him.

Batman: No, it wasn't all bad.

Talia: Then you remember our shared moonlight?

Batman: Some of it.

Talia: *trying to seduce him* The best parts?

Batman: *pushing her away as kindly as possible and also sounding annoyed* Talia, what do you want?

Talia: *walking away* My father, he's dead.

Batman: Ra's?

Talia: How many fathers do I have?

Batman: Sorry, he always seemed...

Talia: Like you? Indestructible?

Batman: Huh, you haven't seen my x-rays.

Talia: *walking towards him* Maybe you can show them to me sometime.

Batman: You don't seem all that broken about Ra's death.

Talia: *walking away from him* There's no time for mourning. Assassins plan to take over Ra's organization. They are lead by a man who father thought could be his successor, until my father got aware of you. Now this man wants to kill us.

Batman: Us?

Talia: Not you. *walking to some curtains* Me, *opening the curtains* and your son.

Batman: Son?

From the curtains, a kid with black hair, green eyes and black ninja clothes appeared trying to look tough.

Batman: You expect me to believe this?

Talia: I assure you, he's yours.

The kid walks towards Batman as he looks up to see his face but doesn't seem surprised.

Kid: Don't look so stunned, father. I thought you'd be taller.

Batman doesn't show emotion but we could already he was a little shocked.

Timeskip

The two Batmans and the boy who was called Damian Al Ghul but his actual given name by Talia is Damian Wayne, looking at Talia's boat go away, but Y/N kept playing Candy Crush, until the two Waynes look at him, as Y/N scratched his throat and put the stolen phone away.

Y/N: S-Sorry.

Damian: *at Batman* You didn't know about me?

Batman: No.

Damian: So mother has made you my responsibility?

Batman: Something like that.

Damian: This isn't necessary, I do fine by myself.

Batman: So do I. But things have changed. She thinks you'll be better off with me... for now.

Damian: What do you think?

Batman: Better than the League of Assassins.

Damian: They taught me how to fight.

Batman: And I take it, not much else.

Damian looks at Y/N who looked at both Waynes.

Damian: *pointing at Y/N* Who's him.

Batman: My adopted son, F/N.

Damian: So he's like my older brother?

Batman: Something like that.

Damian looks at Y/N with a small serious face but Batman touches his belt and the Batmobile door opens.

Damian: I'll drive.

Batman: No.

Damian: I know how.

Batman: No!

Y/N looked at the two Waynes already having a good relationship, as he opens his wings and flies away.

Damian: He can fly?

Batman: The suit can, not him.

They both seat in the Batmobile and Batman calls Alfred.

Batman: Alfred?

Alfred: Yes sir?

Batman: We're gonna have company.

Alfred: A sleepover? Oh, goody.

Batman turns the Batmobile on and drives away. Alfred waits for the Batmobile, as form where the Batwing takes off, he saw Y/N enter flying as he lands in the Batwing pad and takes his mask off.

Alfred: Where are our guest?

Y/N: Gonna arrive anytime soon.

Alfred: Wish to tell me who is it?

Y/N: Would you believe me if I told you is Batman's son?

Alfred: His son? Have I missed anything?

Y/N: Don't ask me, ask Bruce. *walking away to a table* Gonna work with my suit and find a way to go home.

Alfred sighs at him until the Batmobile arrives. The door opens showing Batman in the drivers seat and Damian in the passengers.

Alfred: Welcome back, sir. *looks at Damian* I presume this is the young man F/N and you spoke.

Damian: Hello Pennyworth, I've heard of you.

Alfred: At your service, Master Damian.

Damian: *looking around* Where are the rest of the servants?

Alfred: I am the sum total.

Damian*to Batman* You only have one servant?

Batman: He's not a servant, he's a friend.

Damian walks to the bat computer while Y/N watches from the table with his suit in it, as he looks confused on how will Damian react.

Damian: So this is the fabled Batcave. Grandfather told me all about it.

Damian kept walking with Batman and Alfred looking at him unamused. Damian sits in chair and looks at the computer, but later turns the chair back at Batman and Alfred.

Damian: Smaller than I imagined. Very efficient though.

The two adults look at each other, as Y/N leaves the suit in the table and walks in some long pajamas pants and a white tanktop towards the other two. Damian was now walking in the stairs with hands on his back.

Alfred: He's a spitting image of you at that age. It's a bit chilling.

Batman: Tell me about it. Look, you're gonna have to get him settled. I'm not sure how long he'll be here, but for the time being this will be his home.

Y/N: I smell that this isn't going to turn out great.

Alfred: Me too, let's just hope the worse doesn't happen.

Damian looks at a suit holder and sees some elf costume, with a letter R, being the famous original Robin costume.

Damian: Looks rather effeminate, don't you think?

Alfred: *walking towards Damian* Master Dick was a boy when he wore that.

Damian: Where is he now?

Alfred: Moved on, and so shall we. Would you like to see where you're sleeping?

Alfred takes Damian away to the Mansion, with Batman looking at both of them but later walks to the bat computer.

Y/N: Quite shocking knowing you actually have a son?

Batman: Maybe. Does Damian Wayne exist in the future?

Y/N: Being honest... I've never heard of it. I don't know if it is that the name doesn't exist, or that he is dead or maybe he is still alive but missing.

Batman: Hmmm...

Y/N: Ok ok let's focus on Damian later, is there a way of getting me home? Flash couldn't because of different futures, and a time machine-

Batman: I know... I made a theory on the time machine, I'm not sure if it will work a hundred percent, and is a risky move. *shows a white page with one line separating to hundreds* There's infinite futures F/N, and there's no way to determine which one is yours. Blood test or skin or DNA won't work, infinite futures and in the infinite, seventy-five percent consist with you existing.

Y/N: Then let's look the twenty-five percent left.

Batman: That other percent consists on you not existing or you being dead, none of those are you future. I'm sorry to say that going home will be rather impossible, infinite seventy-five percent is still infinite. The best chance is you having Flash's powers and time travel yourself, either way, it will be rather impossible to go home.

Y/N looks down and later looks away.

Y/N: Is not like I had anything to fight for anyway back in 2057.

Y/N walks away to work in his batsuit, but Batman could tell that knowing the fact he might never return home, might have hit him like hundreds of trucks running over him. Batman takes his mask off and looks at the bat computer again. Y/N stays working in his suit, but this time with slower movement, until he stops moving and grips the suit's glove and looks at it having a lot of visions including: Him finding the suit in an abandoned cave, him in a funeral surrounded by a lot of people of his age, old people as well, and a man carrying a baby and again changes to that same funeral but in the snow, with him having snow clothes. Scene changes to him having karate clothes and putting someone in the ground, another involving putting the costume for the first time, another also involves him beating a thug to almost death with the black gloves covered in blood and his mask having drops of it, like if he was beating someone out of revenge, vengeance, anger. The last one being him in abandoned house holding his mask in front of him and the light shining at him, showing a small bruised face but most importantly the mask covered in blood. Y/N holds tighter the glove as he puts his head in the table and accepts the fact that he might never go home, meaning his entire life was for nothing.
