"Sometimes I don't want to be a savior." Emma was fine with just hiding for a while. Jefferson let her do it as much as she wanted, and she knew it probably wasn't healthy, but Jefferson had seen her through everything so far, and she kept getting back up. Sometimes too early, even she knew that. But he was letting her take her time and God did she love him for that.
Every now and then she wondered what it might be like to not have the magic. If she never got it back after Zelena's curse on Killian's lips took it from her. What would've happened after that? If she didn't have her magic and couldn't be everyone's savior.
In the end she was right when she told Regina that without her there wasn't a savior in Storybrooke. Because she couldn't save Killian, because she was what he needed saving from. "Sometimes I just want to be Emma."
