In the oracion seis arc, they kidnapped Wendy to revive jellal, she remembered him. When jellal sees her he claims not to know her. And then she has a flashback of "jellal" traveling with her for a while when she was a child. And then in the edolas arc, edolas jellal confirms to Wendy that he was the child she met w he n they were young.
Who the fuck is "That Child" Zeref mentioned that Wendy is supposed to meet and get along with?
