[Tony winces at the lizard manages to get Steve's arm, but there's little he can do until Steve manages to free himself. However the moment he manages to free himself Tony is waving his arm at Anthony to handle the lizard. Iron Man gets there to pick the lizard up and then throw it outside the hole leading outside.]

I know you're probably rabies resistant, but I'm sure you're not covered by alien diseases. I'm going to lend you my nanites to hopefully to prevent you from catching anything until we get an actual doctor.

[It's not something up for discussion by Tony's standards as he tries to cajole Steve into giving Tony access to his injured arm. At least they're both still bleeding which will make this easier.]
