I've been feeling, with Vaelus starting to disconnect with Sylandri and finding interest in both Hannan (rest on the path king) and Thaisha, and her forming a strong bond with the faeries (being covered in flowers) and also just. things Ashley as Vaelus has said that she might start a druid multiclass.
Her paladinship to Sylandri is faltering, in any case - so unless her oath is connected more to her lost family instead of her goddess, it seems to me that it's not logical to continue as a paladin without faith. I know Ashley has played a druid last campaign, especially one connected to the world of fey, but I know she has the range and creativity to really change her approach to a druid class this campaign. I think it would be a very natural contiuation of her arc, with the way that Thaisha has been changing her point of view, as well as Hannan. Now that Hannan is dead and Thaisha is going off on her own it might not happen soon though.
