Re: pip
Zeph and Demeter have the housemate thing working out, and since they'll live together, they can become friends. Besides, he's now her adopted son! I don't have any specifics more than that, though.
And we talked a little about Vali on his intro post, so I'll just say I'm still up for them bonding over their similar pasts in this life and then as Frigg and Vali. :D
