"I'll get Lombardi's," Tony said while looking over Bruce's half of the puzzle. He headed over to his side of the lab to tackle the other half and to order the pizza. He knew that Bruce was still new to this and that pushing to talk about it right now was probably a bad idea right off the bat.
Having Pepper there with him helped a lot. Bruce didn't have that support other than making googly eyes at Natasha, before he disappeared into outer space. That whole thing with Natasha was something he wasn't sure he should ask about. What Tony did know for sure, was it helped to keep busy from day one. It helped having things to design, to build, and to keep his hands busy. It kept him from going off the deep end into Crazyville.
And if any place might qualify as Crazyville Central, it was finding out that you're in an alternate universe.
