We Had The "You" Showrunner Break Down That Season 4 Ending

A key part of this is Joe's acceptance of "Rhys." Sera explained, "Beforehand, 60-85% of his energy was spent lying to himself about the fact that he's going to a location to kill someone and then cleaning up the horrible mess that has happened because he hasn't planned it properly. If he instead is more honest with himself, and we're accepting that this is a tool in his toolbox, what does that turn him into? He will always want to be your perfect boyfriend. His belief in love, I don't think, will ever flag. If the Rhys aspect of him is fully integrated, if not, what's in there?"
