[EX Q]: During the Guardians of the Galaxy's visit at the Collector's he opens the mysterious orb and reveals the true nature of its content, being one of the Infinity Stones. But then suddenly his servant approaches the stone as in trance and touches it (ultimately destroying herself and the Collector's den in the wake of this), uttering something like: I'll not be your slave anymore! I wonder though, what dragged her that strongly towards the Infinity Stone? Was she simply hungry for its supposed power, being suppressed all the time (it's established earlier that the Collector isn't particularly nice to his servants) or is there anything more to this, like some kind of unnatural attraction emerging from the Infinity Stone itself (similar to the One Ring maybe)?
[EX A]: What dragged the Collector's servant towards the Infinity Stone?
