Not yet; Idise is going to ask Opoli about the bull's-head amulet and the riddle found in the shrine.  I honestly would rather spend a bit of time in Neathholm.  Aside from obvious purposes like eating and getting some shut-eye to regain spells, it's a good opportunity for interaction and dialogue beyond discussing tactics.  But we're not joined at the hip, so the others can do as they want.
