Zmerr, Ren and Alexis are supposed to help 
Seatan out with some work. Zmerr is planning on keeping a close eye on Alexis because the humans tried to chip him. Alexis' non-human side/ability refused the chipping and retaliated. Alexis, being an archeologist, wants to have a look around the ruins (Zmerr and Ren's home) to find an "orb" that will amplify his power. Zmer is uncertain and that's why he wants to watch Alexis closely. They haven't even started working yet so you really haven't missed much.
