Henry was at school when Mary-Margaret said that they were having a new student, and that certainly caught Henry's attention. "Come in dear don't be shy," Mary-Margaret said motioning in the direction of the door. Henry sat up as a blonde girl stepped into the room wearing a turquoise shirt and jeans with a jacket just like Emma's only turquoise. "I'm not shy. Just curious…" Said the mystery girl while looking at Henry. "Do I know you… Henry?" The girl said a little hidden suspicion that only Henry could pick up in her voice. "How do you know my name?" He questioned. "Who are you and how did you get to Storybrooke?" Henry had so many questions firing through his head, and like the mad hatter on a sugar rush he just wanted to scream them all out at once. "I got here the same way your mother did." She said. "You're not from here are you?" Henry wanted answers. "That depends… is anyone?" The girl was too clever for Henry so he decided to be quiet.
"Umm, how do you know Henry?" Mary-Margaret finally broke the mystifying silence. "I know him but he doesn't know me," she said with a smirk. "Okay class this is…" Mary-Margaret trailed off not knowing the girl's name. "Heidi," The girl answered to Mary-Margaret's questioning gaze. "Well Heidi since YOU know him you can sit next to Henry and he will show you around the school," Mary-Margaret exclaimed emphasizing the "YOU." "Yes mam," Heidi said looking down and walking towards the empty seat next to Henry, but before she could sit Mary-Margaret, looking at some papers, cleared her throat and said "Umm, Heidi do you have a last name because your records don't mention anything and you have no emergency contact or any previous records at all for a matter-of-fact. Henry's right who are you?" Heidi looked out the window before turning back to Mary-Margaret and said, "wouldn't you like to know."
Heidi sat down and an extremely confused teacher continued with her lessons for the class. As the bell rang everyone left but Mary-Margaret asked Heidi to hang back and talk to her, eat lunch in her room. Heidi reluctantly stayed but she had grabbed Henry's arm and said strongly, "I'll stay but Henry stays with me. Afterall, he is my tour guide and I would be lost without him. Especially if you decided to let me go to the cafeteria at some point." "You are very persuasive," observed Mary-Margaret as she and Henry unpacked their lunch boxes and started eating.
"Heidi where's your lunch?" Henry asked. "I'm not not hungry," Heidi said looking down. "Growing girls have to eat. Here," Mary-Margaret said as she handed her a peach. "Thanks. How did you know I love peaches?" Heidi said. "Oh, you do? Most people around here hate them. I didn't think about it when I gave it to you, but I'm glad you like them," Mary-Margaret exclaimed with a bright, beaming smile. "You know, I think you're the only one besides me, Emma, and Mary-Margaret who likes them. And I used to think it was a family thing," a secretly confused Henry stated eating a peach. "Who says you were wrong?" Heidi questioned confidently causing Mary-Margaret to spit out her drink. "What are you two talking about?" Mary-Margaret asked almost worried as Heidi and Henry just stared each other down. "Okay, you two have been talking weirdly and been questioning each other the whole time since you've met saying strange things like you're speaking your own language and I demand to know what's going on," Mary-Margaret sternly commanded waiting in silence until Heidi spoke. "You have let go of your childhood Ms. Blanchard, for the language we speak is foreign to no one. It is the language of imagination and belief. Not many adults hang on to it even though they never lost it." Mary-Margaret had a blank expression on her face and just watched the two almost slightly similar children stare at each other then said, "You know, you're smart but very confusing." "Thank you," Heidi commented with a hint of pride and sarcasm lingering in her tone. "Now to answer my question," Henry stated, " who are you?" Heidi was quiet for a moment contemplating whether to tell the truth or not until she finally spoke up, "I'm Heidi, Heidi Swan…"
