Love maybe not but friendship is definitely possible. Just like a friendship between Molly and Kringle is possible. It has become clear that Mab’s ideas about these things are not absolutely how it has to go and all previous preconceptions are not necessarily always true.
Mab and Kringle, we are talking demi-gods and gods here. Not ordinary people, Murphy isn't going to remain Murphy in the Halls of Valhalla, not even close. Remain friends? One has to have a relationship for that, they won't. I repeat, if there was hope for any of that, Gard would have said it.
She lost a lover in Hendricks and a friend in Murphy as well, she, herself is immortal, she said, no.
