Don't think so.

Haven't they confirmed a few times that there would be no AV hm?

And I think that they will simply be rivals for the Doman kids to prove their usefulness, and be some lighthearted quest until we get Hildy again.

And wasn't the monster thing just a distraction for them to run off? They did some fake summoning thing for Valefor, knowing that our WoL was a primal killer and would probably take it seriously.
