I don't think she was any different to how she has been before. She has a very sharp tngue when she gets her dander up. Clearly she doesn't like Tony and he feels the same way. He is a grown man, I am pretty sure he can hold his own.
I don't know why he made such an issue about the bug on a show where people eat live cockroaches and witchety grubs which imo is far crueler that a quick death on the fire.
Surely he knows this about the show and knew he might have to potentially eat one in a trial if chosen to do it?
