She became obssessive with a man to the point she’s willing to endanger her family and leave Storybrooke unprotected (she’s the savior of this town, doesn’t that mean anything anymore?), all of this she does for a guy, that’s being selfish towards every other character in this show. A strong character wouldn’t have gone to the underworld, she would have delt with the loss and let her family be there for her.
Ok, but the town isn’t in danger right now. And can you blame her for wanting to try and save someone she loves? Someone who’s death she blames herself for? As far as I know, she didn’t ask her family to come with her. They all just sort of went. I think a strong character WOULD go to the UW if she knew there was even a slight chance of saving the love of their life. Just accepting it and not trying to do anything about it, when you know there is a chance, is losing hope, which this show loves so much, and basically giving up. If she’s the savior, GO SAVE YOUR LOVE. The town is fine. I think it’s important to note that Emma being The Savior always meant she was going to save “them” (her family, friends, etc.). They all happened to be residing in storybrooke. But she is not the Savior of the town. She is the savior of the people she loves. She is going to bring the happy endings. She saved them by killing Hook. Now the town is fine. So go get your happy ending with Hook.
