So I’ve got a whole list of things that would have changed the timeline but somehow didn’t.
1) Emma stops her parents meeting resulting in a Ball thrown for the engagement of James and Abigail, during which Snow White breaks in, Regina’s black Knights have a sword fight, and an unknown Princess gets captured. How does that not change the timeline? You could argue that the ball would have happened regardless, but certainly the fight would not have.
2) Hook met Snow White in the enchanted forest. Wouldn’t that screw up the timeline for season two. Why didn’t Snow recognize Hook from the Enchanted Forest after she and Emma got sucked into the hat. Meeting him literally resulted in her being burned alive.
3) Snow and Regina meet and above burning happens. Even though Snow escaped unscathed, am I really supposed to believe that this event would not have altered Regina’s strategy toward dealing with Snow. In this scene, Regina learns that Snow is willing to use dark magic to kill her. Wouldn’t that put her on guard? Would that alter her strategy? And Snow. Would Snow really be so quick to stop Regina’s execution when Regina BURNED HER ALIVE. WTF.
4) Rumble doesn’t question why he’s holding the black fairies wand in his dungeon? Where did he even get that, I thought Blue had it. And he doesn’t notice that Elsa’s urn is missing.
5) Regina doesn’t question it when prisoners go missing in her dungeon?
Ugh So Many Plot Holes.
