zobelle and his daughter kiss

There was another observation from the last episode of Sons of Anarchy that I noticed, or maybe I just didn't want to acknowledge that I noticed it.

Just before Clay, Jax and company finally move in on Ethan Zobelle's cigar store for what will presumably be their final kill, Ethan and his daughter share an uncomfortably long kiss.

Granted these two think they are going to have their brains splattered against the walls by their scorned enemies and are in fear of their ever-loving lives, but the kiss they shared seemed to suggest that something else might be going on between then. So...
