Spoilers for the Netflix Original show Trollhunters, seasons one and two

Everyone says that Jim has troll blood. I disagree. I think it's Claire that has troll blood.

First of all, I know she's smart, but how did she grasp troll knowledge so quickly? Was it because it just came naturally to her through blood? Maybe.

And why did Vendal take a liking to get so quickly? It took him months to start to even consider Jim as a worthy Trollhunter, let alone start liking him. But with Claire?  One sentence in the troll language and he'd already welcome her warmly to Troll Market (Trollmarket?)

And the language. Claire already seems pretty fluent in Trollish, and the gang hasn't even been at it for a year yet(according to season two)

Also, Claire has made huge portals before, like her first real portal in Jim's house, and the one when she, Toby, and NotEnrique were getting Killahead(?) bridge out from the ocean, and her portal in the season/part two finale (In the Hall of the Gumm-Gumm King) her portal isn't even a real portal, it just grabs everyone in the room and teleports them
(Also, I have a theory. It wast the portal that made Claire possessed, it was how the teleportation worked, cause there was no portal, it just grabbed everyone and left.)

And finally, the Skathe-Hrün, better known as, the Shadow Staff. Claire seemed to begin to understand it pretty quickly, and she gained control over it and started to be able to us it effortlessly in just about two months. It took Jim way longer to get a grip on his armor.

The evidence isn't the best, but it works for me
