Or if Shadowheart doesn't come with you, have her taken to Moonrise, where we're heading anyway. Or have the Absolute's mind link work...putting us on the path of looking for The Weapon. there are so many ways you could write around this that don't involve, falling rocks.
As it is, I will say that characters who aren't interested in everything related to their tadpole and the absolute can be said to be working against their own best interest. Waving a mysterious box under our noses is enough for most people to be interested, but it becomes a little unseemly when you start doing it repeatedly, before violently clobbering us over the head with it.
