I'm thinking that Kellhus might be able to do a variation on far-calling--but take it beyond dreaming states and do it wherever he is / wherever they are.
Also, it struck me recently that one of the main reasons to put Sammi in the story was that the twin-staring-thing carried Kelmomas right through the early years until he was bigger and had more control over himself. In other words, he might have behaved similar to Inrilatas, or at least showed that he was super talented, but he spent the whole time staring. It allowed him to seem 'normal' to Esmi and somehow 'like' Kayutas and Theli who apparently flowered more gradually. In other words, Sammi protected Kelmomas from Kellhus' scrutiny until it was too late.
I like Theli. If she's scheming to be the last Anasurimbor standing, she's doing a heck of a job.
