Thanks so much for your detailed comments! Yeah, I guess I assumed that since they were obviously faking it to push Sereda's buttons, it wasn't "real" slash or incest, and wouldn't require either tag. My bad.

The sad thing is, I don't even care that much for slash myself in fanfic. It just jumped out at me and said, "Hey, here's a way to get under her skin." I'll know to tag it next time.

Going back through it, it's ridiculous to try to pawn this off as Alistair's dream when there's so much of Sereda's POV in it. I either have to rewrite her parts or redo the ending. I'm guessing I'll go for the latter, something along the lines of what you've suggested, which will fit better with regard to tone.

Again, thanks for taking the time to write this up. It's a big help.
