Well, all his ideas right now are catching someone who came out of what seems to be a gathering house of sorts and make them give up some information. But he doesn't need her for that.

He looks around the place. There's nothing that he could tie her up with to perhaps use her later, and if he disables her from walking she might start shouting for the people below. It might be best to just kill her and leave her up here - the place looks like nobody has been here in ages so she should take a while to be found, and he has the gifts to make it look like someone stabbed her instead.

"Maybe."

He's turning towards her now, still crouching down, his left hand crossing over his feet to in a few moments be placed on the ground on their other side. The look that he is giving her is definitely not pleasant - there is no malice in it, only the look of a predator about to go in for a kill.

"They don't include you, though."

She simply is of not enough use to him to let her run around any more, and even if he didn't figure that killing her would be a good option to begin with, he couldn't let her leave with the knowledge of him being around, and what he looks like. Even if anyone else also witnessed him to remember back in that arrival place, they only saw his Crinos form, after all. She's seen almost all of them, now. And besides, he's hungry, and there's prey right before him. Why would he not?
