When Sam turns his head to look at her she stops moving, like a deer in the forest. Although she could toss a mighty glare at him if she wanted to, she can't help but see that he's ill or perhaps injured. Yeah, it's pretty pitiful looking, Sam. Especially when even an alien can tell.

"Are you alright? What's wrong with you?" It's not exactly... sympathetic. Her tone has more hints of caution than concern. Gamora looks him up and down, trying to assess for herself what the problem is, but he doesn't appear to be bleeding or anything. He better not have some kind of Terran plague.
