This one is good. The Repunzal is Elsa and Anna's sister theory never made sense and had way too much reaching. But cousins def makes sense. \n\nI don't think Agnar was ever interested in magic though, given how he reacts to Elsa's magic (and he never goes back to them in later years either). I think he knew where to find the trolls because of his sister. Arianna was the explorer and researcher of magic. When they were children, she dragged him along, at some point, or maybe more than once, he met the trolls with her. That's how he knew to find them later.\n\nAlso this makes sense as to why Gothel couldn't eat the flower herself and retain its power. Clearly there is some sort of magic in Agnar and Ariannas family line. Not everyone has it but it appears in some. So that's why the cure helped Arianna (but didn't fundamentally change her) but Rapunzel had some gene or trait present within her that allowed the magic to take hold in her. (something that was dormant in Arianna but became activated in Zel)
