Eileen's still at the point where she doesn't know what to think of Greg. He doesn't look like he's ever killed anything in his life and he certainly doesn't seem dangerous so she's just sort of staying out of his way and keeping an eye on him for now.

If approached, she'll be polite enough but probably won't have a lot to say to him. He's nice to the ratbird, though, so that's a point in his favor.
