You know how Bruce says he's put a bullet in his head and the other guy spat it out? And how Steve had the look of a worried friend and Tony had the look of someone who tried it before?

The workshop is dead silent. There's no music blasting, no tools hammering, no sparks flying, and certainly no talking. Tony and Peter sit at their respective workbenches in silence. Peter is upset but won't tell Tony why. Of course, they devolve into a full blown argument.
