Right. As I said. Selfish. It's nothing but escapism. No different from one crawling into a bottle. It was never suggested, at the very end of the episode, in any way or form, that he honestly thought he was being a father to a real child. No. He just said that the fake daughter, the one he came to fully well know was fake, felt real, to him. It felt real. It made him happy. Not his daughter. That's him being utterly selfish and wanting another fix. Nothing more.
But I mean, hey... That's just how I saw it personally. That's what was completely obvious to me. You're free to have your own interpretation of it, and it's honestly pointless to debate it. I just wanted to gloat over the Mr. High Horse guy falling from his pedestal, and I did that. I'm sure he won't die in the end, but if you ask me, the show would be better without him. Again, just my own personal opinion, and I'm sure I'm alone in thinking that.
