How would Meritxell feel about getting, like, forcibly subdued and dragged off to a nearby simulated cuddleroom by Keltham? He's getting a surprise ready for Carissa. Meritxell shouldn't use magic, but should fight back as Keltham as hard as possible except for that part.
This is not a strong social request, to be clear. If Meritxell would rather not get hurt that way, or would feel weird about going all-out against a cuddling partner, Keltham will ask Pilar. He almost did that anyways, just, his social model suggested that Meritxell would strongly want to be asked even if she said no, leaving aside his not-to-be-mentioned-in-advance probability that Meritxell will say yes.
