This takes place after Bruce washes a shore after a battle he had with Braniac, who died in the explosion . It takes him four years to return to Gotham, and he has only one thing on his mind...his boys.
He has a very vauge recollection of what happened, he tries hard to remember the occurrences of that fateful day, but all that comes to mind is an explosion and something Braniac mumbled about "festivites". Normally, this would be the most important this rummaging around Bruce's mind, but at the moment something of much greater importance has come up.
He checks his body, and he is suprised to see that his body lacks any noticable scratches, save for the large gash across his upper back. He catches his breathe and notices a smell that would be otherwise unpleasant if not for its hint of familiarity.
"Gotham Docks." Bruce says faintly through panted breath.
Once he has collected his bearings he begins his voyage, but not before he approaches the homeless man at the Docks. Bruce looks at him, surveying his height and weight before he speaks, but before he gets the chance to release a single syllable the man speaks first...and rather excitedly.
"Y-You're B-Bruce Wayne!" Bruce Nods.
"I need you're clothes."
"What do I get?" Bruce chuckles at the man's blatant question.
"Come to my manor tomorrow, we'll discuss things there."
That man nods and proceeds to give Bruce his clothers, which he accepts and begins his long march home.
As Bruce continues his march wearing nothing but an oversized blue hoody, riddled blue jeans and comically worn out sneakers, he begins to notice something odd about his city...It's remarkably clean.
He rattles his brain about this as he reaches the gate to his home, he jumps the gate, takes a deep breath and knocks vigourously on the door, instead of using the perfectly fine buzzer near him. But he has a deep-gut feeling that something is...different.
