I honestly don't know. I will get in touch with the TB cast about this. I really would like to get some family bonding in before canon resumes and everything goes to hell. Lilith will hug him upon meeting him. She considers him a very good friend and clearly good friends should be hugged!

Good then! Caterina will enjoy chatting with him and taking in the sights. Since Iblis arc is coming up hints of her illness will be in the conversation. (Basically she'll cough and blame it on the new environment.)

Oh like I was telling Peter-mun Jacob would not kill him. He only kills vampires. At worst, there will be some maiming if he walks in on Claire getting hurt or he tries to get in the way of rescuing her. Jacob will be furious but, protecting/removing Claire will be his priority.
