So Max looks like Luke and I think he is his reincarnation. That's why he doesn't like it when she doesn't look at him anymore. He fears she has changed. But I can see that he had ignored her in the past.
Let's see how it all unravels.
luke - max
rose - lexa
tubby -
waiting for the guy that probably took care of lexa when luke married someone else.
altho I like Max. Tubby probably deserved her more.
