Once Upon a Time actress Jennifer Morrison talks tonight’s episode, “An Apple Red as Blood,” and hints at the season 1 finale in a new interview. Beware of spoilers.

Speaking to TV Guide, Morrison explains what causes Emma and Henry to stay in Storybrooke despite Emma wanting to leave at the end of last week’s episode:

[Henry] actually takes the wheel while she’s driving and causes them to crash so they can’t leave town, which obviously really freaks her out. She’s like, ‘My God, you’re actually willing to die over this! You’re 10 years old — how can you be thinking this way?’ Obviously, that’s a big eye-opener for Emma. If this child is that extreme about it, she obviously needs to take a step back and figure out the best way to make sure she keeps him safe and does the best thing for him.

Speaking about the finale, Morrison has some really interesting things to say:

It’s so massive and so game-changing. I mean that in the best way. I read the season finale and went, ‘Oh my God! What is going to happen?!’ […] Thematically, there is going to be such a drastic shift that it will be a whole new adventure [in season 2].

She also promises a “serious amount of growth” for Emma before the season ends, and confirms that the stakes will be very high in these last few episodes. Looks like everything really is going to change, doesn’t it? What do you think the writers will do to keep the story fresh?
