Bruce hadn't trusted himself to dive right into whatever was being worked on, so he lurked on the outside and simply watched and observed. The labs weren't staffed completely (one or two people were around), but he was sure that was just because New York was still and iffy area to be in and most people hadn't returned. If they ever returned. Bruce tried not to think about that (weren't New Yorkers supposed to be a bunch of arrogant, stubborn people?).
At the moment, he was leaning over one of the abandoned work spaces, reading through notes someone had left behind. They were good. The math was off, but they were good. Before he realized what he was doing, Bruce had taken a seat and pulled out a pen to fix mistakes and rewrite a few things.
