Summary: An exploration of how Tony tries to understand Bruce, while Bruce tries to understand himself as the Hulk.

Yesterday, Bruce thought a spark had caused him to lose Tony. He'd been overcome with fury and overtaken by memories in deep, cold blue, but then a momentary memory had illuminated all he needed to know. Upon his arrival, he knows he is home. Author's Notes: So, as I was trying to reign in all of my ideas for the amazing Science Bros Week, I realized that it would be easier if I did one whole story in sections that were based on each prompt. So, I will be posting each section of my story in the tag sciencebrosweek. Enjoy! Also, I'm sorry for how sad this gets. But, I do feel like the characters behind Bruce Banner and Tony Stark are fundamentally flawed in ways that don't always get explored, so. Happy Science Bros Week! :)
