A round character has many traits
the last one is the answer , since the person is trying to show how they fought and trying to make you feel impressed by it!
A suspicious character might:
- look around suspiciously
- look at the time a lot/or phone
- disappear into a corner/something
- look suspicious
- walk around glaring
those are some ideas, i hope they help :)
I think it might be “It introduces the story and sets up the coming events.” I’m not sure so take this with a grain of salt...
