Okay, so I'm a bit late with jumping on the plot train...

FH canon-wise, Isabel has already established that healing is not her thing. But she can research if needed, and don't forget her ability to get into people's dreams. It's easiest if a picture is used, but she can get into someone's dreams when she's awake, it just takes a bit more concentration. So if Angel feels like throwing a bad dream into the mix, she's available for calming purposes. Otherwise, tell me what to do.
