Random ‘Trollhunters’ Theory
Ok, so in Trollhunters we’re shown in episode 03 how the amulet will not allow the Trollhunter it has chosen to refuse the mantel once it has become bonded to them. Even if the Trollhunter attempts to reject the amulet, it will always find its way back to them via flight or teleportation. It seems this is the rule so that there will always be a Trollhunter to ensure the safety of the good trolls and of mankind no matter what.
We then find out in episode 04 that the amulet can/will magically return to the Trollhunter only if the Trollhunter rejects it, and that it cannot/will not return magically if it’s taken away from the Trollhunter by force (ex. when snatched away by a thieving gnome).
So…why is this? Why does the amulet not return to the Trollhunter magically if taken away by force?
