Here’s what I think. The flashback takes place right after 7x08. Henry and WHook decide to voyage across the ocean. On the way, they find two merpeople, Hansel and Gretel, who have been recruited by Gothel to steal from an underwater Blind Witch. They eventually succeed with the help of WHook and Henry, and Hansel and Gretel give the item to Gothel. Gothel then reveals that this was a test and that they had succeeded. She then trains them in magic, and has Gretel eventually join the coven.
