Candyland
Bruce agrees to stay in Stark Tower for a few days, until he can organize his next 'trip'.
When he sees the famous ten floors, well, it's hard not to gape. He knows what most of the machines are – has heard of them, at least – but to have them all in the same space, no matter how big, it's dream-like and mind-blowing and exciting. But it isn't enough to make Bruce stay, no amount of money and blackmail is going to make him endanger New York again, it's had enough destruction, he tells himself.
Tony tries: he tries bribes and pleads, he tries threats and shouts, tries again and again during those few days, but Bruce still buys a one-way ticket to Pakistan.
The night before he's supposed to leave, he goes down to pick up a few little personal items he's left in the R&D, and finds the room literally flooded with sweets. 'Welcome to candyland,' a banner hanging innocently from the ceiling says.
Bruce (both him and Hulk, in fact) hasn't felt that – blithely amused, he thinks, putting a banana split taffy into his mouth – for months. No, make that years.
Maybe he should give it a try.
