my theory is that keith is actually not spending time with his family but locating/ will fight with christine. I think this time Itll be Keith who will get hurt and First will have a big meltdown and realize he really does love Keith that way and does not want to lose him.
Keith probably has regenative powers or just powers anyway that can combat vampire blood or could be that he has vampire blood in him thats why hes given his name but still being despised.
