I would imagine it doesn't turn out well in the end because of the events in 7x02. I mean what Wish Hook told Real Hook is very clear when they first met. He also didn't even bring up the mother while dying just his child. And if he had TL or anything with the baby mama he would have never gone to the lengths he did (trying to kill Real Hook,going to Tremaine to masquerade as our Killian and then be with Emma) if that was the case. He did all those things.
1… You don’t have to have ‘True Love’… or a ‘fairytale epic romance for the ages’ to be in a sexual relationship and/or create children. That doesn’t mean you were tricked into it, or worse. You can care very much about someone, or just like them a lot, or even just be attracted to them, then stop feeling that way. Take it from me.
2… WH knocked Killian out so he could trade places with him, he didn’t try to kill him. If he’d wanted to kill him, he could have. And, reading your mind, following that storyline to it’s creepiest end, like can’t anyone take anything at face value instead of assuming he planned to desecrate Emma? Maybe he was just looking for a kiss to break his curse? OG Killian understood and forgave him, Emma understood and forgave him, and so have I.
Look, I don’t know what’s going to happen tonight and I DON’T CARE. If Killian 2.0 shacks up with Rapunzel then yay! If he doesn’t, yay! If he makes out with Smee? Yay! I’m still watching. I LOVE ALL VERSIONS OF KILLIAN. I LOVE COLIN O’DONOGHUE, for his beauty and his ability and because I think he takes his job seriously and I’m behind him 100%. Captain Swan is safe and comfy in Storybrooke. What this Killian does has nothing whatsoever to do with their happiness.
