After Lucifer and the others got alastor back from the auction, and now own his soul, alastor tends to follow either Lucifer or Charlie like a duckling while wrapped in a blanket. Alastor head butts Lucifers' shoulder bone softly

(He is clingier than normal and had been missing and hurt for two months before getting saved. Alastor is a deer demon. He has deer hooves on his feet, claws, sharp teeth, a deer tail and ears, and antlers)
