Alas, I've promised Hawke a ridiculously large stuffed bear, and a ridiculously large stuffed bear she shall have. That, and I do not want to be reminded of Karl any more than I already have been.
I'd point out that we don't actually know they can't get us home, do we? My bet is still on someone or something here controlling the Portals, which in many ways makes this easier - we figure out who that is, we have an obvious point to push until it bends or breaks start working on. But I'm prepared to be proven wrong.
