Well if he doesn't maybe it will be the push Lucas needs to cut him out of his life. I wasn't so happy when Sam got in his face to pretty much told him what to do but maybe if Julian doesn't approve, that will seal it for him to stop talking to him.
Then yet I don't think Lucas would actually go to Julian and tell him hey I'm dating a guy so how's your mob biz going, pops?
I would think they have a long road ahead to build up a relationship to even get to that point.
Does anyone else just hate the word "partner" when describing a romantic relationship? Maybe it's just me, but the word just brings up connotations of business dealings and school projects. Hardly romantic... :]
