While the pair are off checking around the building, Gwen makes sure Rob is all right, checking vital signs and so on to make sure the spirit's possession hasn't had adverse effects. Or obvious ones at least. Here's hoping he doesn't remember what he was.
When the others come back, and Vincent makes his 'report', such as it is, Gwen nods, numbly. "All right. He can't stay all ghost-like for long, so we'll get him another time." She hoists up Rob, debating where to carry him. "At least it has to start the possession all over again. We'll come back in the nights to come, find it again. We'll bring a book of law next time." Which is probably one of the most cryptic things she's said in a while.
"Come on, let's get him somewhere safe, then it's back home." A part of her starts thinking on exactly how to handle 'Rob'. It would be lying to say she didn't have a few ideas. But she would reserve those for when the pack was ready.
