It's good you don't have to rebuild up from the bottom alone. Are you glad to be back to working? ( The pretzels are probably grateful too, but it's good to see Fitz getting back into what he's so good at doing even if he also forgets to do other stuff usually while working so intensely. He glances at the equations, opens his mouth and closes it again as if he was going to say one thing but then it got lost along the way. ) Looks like you dove right back in.
