I enjoyed this episode, but it's one of many episodes that raises one of my biggest issues with this show - that Patrick is basically a wish-fulfillment dreamboat.
He has no flaws, aside from a few hiccups about coming out of the closet. Why did this smart, handsome, charming, ambitious man (with a Broadway-quality singing voice) move to Schitt's Creek again? So that he could work for Ray, and live with him? Huh? Even if he was just trying to get away from his fiancee, this seems like the last place he'd choose.
I don't buy for a second that David, stuck in the middle of nowhere, would luck into finding this ideal guy, who just happens to find David's selfishness and snootiness endearing.
It would all be a lot more plausible for me if he wasn't so adorable, and he was dealing with some serious issues of his own. Like, say, he was living with his parents while recovering from a substance abuse problem. It would take real growth on David's part to accept someone like that.
