Thellim is not liable to notice this mystery. It is too obvious for her why somebody would be unhappy.
:It seems very, very unlikely that Vanyel is the perpetrator here. That being the case, I think we deal with Vanyel's ongoing actual medical issues, and only later figure out later what to do about the giant mind control plot by mages or gods or both. It's at least conceivable that what we're looking at is consensual, although the way that Yfandes was freezing up during questioning does not look like the sort of mental help I'd ask for myself. And, though I hate to say it, depending on how the mind control works, it could very easily be integral to who Yfandes is now and ripping it out could be the equivalent of killing her and creating a different person. For all we know. Too many complications drop all this. We should go look at the place where Yfandes is joined to Vanyel, where she's supporting the broken lifebond, before we look at Vanyel again.:
