If she is dead/kidnapped, I think the Witch has something to do with it. If not, then I expect it to be accidental. Would definitely be more tragic if Tremaine is Rapunzel and was incapable of healing her daughter.

Guessing this might be the flashback to kiddie Drizzy, Ana, and Jace. Perhaps it will support whatever 7x08 is about.
