Genji is considering his options here. Peter is probably the closest thing to a cyberneticist that he'll find in this place and he also said that he works with nanotechnology. So should anything actually go wrong with Genji's armor he may be the best one to ask for help.

Though on the other hand heh that also means letting someone see how Genji's armor is constructed which could expose weaknesses. But it's also Peter who looks like he'd probably break into a cold sweat if he had to jaywalk.

Retracting the plate he holds his metal arm out, palm up as an offering that Peter can inspect it if he wants, "Yes, but you cannot take my arm apart. I need it."
