Dillon here is a vocal coach and once sang opera. He is also the proud father of 8 year old twins Elizabeth Catherine and Timothy Harrison. He is still madly in love with his ex-wife. I have him written down as the delusional ex-husband, because he still has hopes for his relationship, albeit they have been divorced for 7 years now.
I see that the single divorced guy thing could be a commonality although I don't know how they would have become friends.
