Remember Emet also seemed to just want to nap. What kind of primal would just go and allow a tempered subject to just float in the rift and be all nah I did my job and now I'm just going to float here and wonder if I'll dissolve into nothingness. At least that's what I got from that tale from the shadows that even before we killed him he'd just go and do that.

He seems to be the kind who at least over the many years would do what he had to do in order for a rejoining to occur, but after that was done go and do whatever he wanted. Even if that might have been just napping or looking at the memory crystals. Or trying to find any hint of his two friends in the lifestream.
