Riding imaginary dragons, dispatching with dear old Dad and going vroom on a broom are just some of the more challenging scenes that Once Upon a Time‘s stars have tackled over the course of 100 episodes.

At the ABC drama’s Feb. 20 party in Vancouver to mark the milestone, TVLine invited the cast members who walked the red carpet to name the scene-to-date that had been the most difficult to shoot — either emotionally or physically.
