What just happened? was the first thing that cross Alexandra's mind. Let's get this straight. First, this new guy comes in. Second, this new guy stabs the old (old as in he was here before) guy in the foot. Third, the old guy leaves. And, last, this new guy claims to be Calliope's uncle? Something is messed up here...
Alexandra, assuming this man had been following them for a while (since he wouldn't coincidentally be in the woods when his niece just so happened to be in danger), didn't bother to hide. Standing up and leaning against the tree to hide the pain in her foot, Alexandra said, "Why don't you come over here? I'm not going to walk into a man who has a knife in his hand and just stabbed someone. And neither is Calliope." Alexandra was grateful towards this man for helping them, but she added a little bit of coldness into her tone. He was way too suspicious for his own good. For anyone's own good.
Looking over at Calliope, Alexandra silently whispered, "Niece? You didn't tell me you had family following you. Who is he?"
Alexandra was in a bad mood. And she had every reason to be (at least in her opinion. She was chased out of her camp by a gigantic bounty hunter (assuming he was a bounty hunter), then she had to go to the guy wanting to capture her to get Calliope's stuff, and then she had to run from him. If that wasn't bad enough, he was also a better runner and tracker than she thought, leading in her getting almost cornered. She then sprained (she thinks) her ankle, and now she's stuck with some obsessed stalker uncle trying to help them. Yeah, she had every reason to be in a bad mood.
