Note: this is in the same continuity as my other OUAT fics, in particular The Storybrooke Dodger which explains Frederick's adopted son. Dodger, who was adopted by Emma in that story, will soon appear in this fic.
Robin's muscles were developing faster than she could cope with. Her body wanted to run but her mind was barely used to walking. Snow and Frederick had some ideas to help Robin keep up with herself. Zelena took Robin to see him at the school gymnasium. Zelena held Robin's hand as she walked. Robin was glad to meet a new person, especially one that was going to play challenging games with her.
"I hear you're having some trouble with moving around?" Frederick asked Robin.
"yeah" Robin said.
"My nephew, Henry, calls it the Raichu Effect" Zelena said "Her fast development makes her miss out on learning certain skills before advancing".
"Well, let's practice walking" Frederick said, taking Robin's hand. They walked around the gym, small laps at first then a little bigger.
"Do you think you can do this on your own?" Frederick asked Robin partway through a lap.
Robin nodded, confidently. Frederick let her hand go. "Show me" he said.
Robin finished the lap on her own and gave a triumphant grin.
"I bet you can't do a whole lap" Frederick challenged. Robin showed him by walking a whole lap.
Next Frederick challenged her to chase after a ball. She had fun for a while, until one of her attempts to grab the ball made her fall down. Robin was frustrated and threatened to turn Frederick into a flying monkey.
"Robin, be nice" Zelena chided, then she turned to Frederick "I'm sorry about that, I don't know where she learned that".
"You don't?" Frederick questioned "It sounds like something the Wicked Witch would say".
Zelena looked embarrassed.
"I have an adopted son, Harry" Frederick told her "He learned some bad stuff on the streets of Dickens' realm. Kids pick up stuff more than we tend to realize. But Katherine and I try to be good influences on him".
"Are you accusing me of being a bad mother?!" Zelena said angrily.
"I just think you need to be more careful of what kind of influence you have on her" Frederick said "especially with her accelerated maturity".
Zelena knew he was right but was too angry to say so. She didn't have much experience taking any accountability for her mistakes.
"I'll see you next week" she said begrudgingly, then took Robin home.
