Jack looked down at the large amount of money with a bit of awe.  he'd never actually seen that much money in one place before.

"I can't really take all the credit," he shrugged.  "For some weird reason it was like I could see the future during the fight.  I think maybe god was helping me.  I dunno.  Probably not.  They say god works in mysterious ways but... I really hope not [i]this[/i] mysterious.  Well replacing the lock wont't be a problem anymore.  Going to have to rebuild these too..."

He removes his waterlogged shoes, literally pouring the ocean water out of the boots.  He'd say something optimistic like, 'Well the sea water couldn't have screwed them over any worse than they already were right?'  But actually it probably could.

"I could probably come back with a mask and something other than the boots.  I could afford some materials for that Unobtainium catapult or something now.  But um... yeah, no.  I'm out of this business."

Jack goes home.
