I just think it's highly unlikely that two people have gotten dragged into... wherever they're being taken and that they're both going to come out unscathed. I think that since Will's a kid, it would be pretty brutal to kill him, not to mention he's been the characters' main focus ever since he disappeared. But we haven't seen the response to Barb's disappearance yet, so maybe I'm just jumping the gun here. I just suspect that Barb won't get a happy ending here, but again, this is just speculation.
