Yato will probably ask to see Thanatos and Jack Frost with a vague explanation as to why leading up to Christmas

Then LO AND BEHOLD Elizabeth will receive a pair of small figures whittled from butternut wood, one of Thanatos and one of Jack! Because Yato has regained his stupid over-the-top art skills from canon, they will be pretty accurate caricatures. They'll have sturdy bases for easy standing, and underneath each will be an inscription of the date, Yato's signature, and the names of the personas in case Elizabeth forgets about them someday. #justretrospecthings
