It was really kind of Priscilla to keep Vae warm for them while they were away.
I like to imagine that Priscilla really enjoys playing up the cuck angle even though she has explicit permission and knows everybody's okay with it. Like, she'll be like "ooh look at me I'm fucking you're girlfriend loser" and Caelle is just like "Yes, I specifically asked you to do that, keep up the good work."
