Emma isn’t a coward nor is she scared. She like she said, “did not sign up for this.” Pinnochio is to blame for all of this. Had he not left her she’d believe. He made a promise to stay with her after Geppetto extorted and played everyone’s life in FTL to get Pinnochio into the wardrobe. When you have lived a certain way for 28 years and one day you are expected to believe that FT characters are really, you are a daughter of two Ft characters, your son finds you and tells you all of this as well as saying you need to save everyone in FTL, how is anyone to react? “Yeah Ok. I’ll just go save FTL. Let’s go.” She’s reacting like anyone who has just heard the most outrageous story and was expected to believe it. She needs to see it first hand.
