1)Pariston is Sheila
they look extremely alike, Sheila wanted to become a Hunter, Pariston IS a Hunter, Sheila has the rat ears, while Pariston is the Rat Zodiac
2) Sheila(Pariston) didn't get lost in the woods, he was searching out the area for the Kurta clan
>To show her gratitude, she gives them a book*, which is really weird and random since they don't speak or read the language(was the book some kind of tracking device or had a chip in it?)
3)Kurapika's (seemingly) fatal mistake
-Pika's seemingly fatal mistake was when he was on his mission to the 'outside' with Pairo world during the test, when he got mad and his eyes reddened. A bunch of people saw this and word must have gone around. He didn't inform the elder about this, so , in his mind, when he heard of the massacre, he thought it was his fault. Why do I say he 'thought' and not 'it WAS his fault'?
Because of the tracking device in the book Sheila(Pariston) gave him. That book was actually the reason the Troupe managed to find the Kurta village, and not the fact Pika had his 'outburst of red'. Pika doesn't know this and it only amplifies his rage and creates terrible self hate and blame, since he thinks the massacre of his kin was his own fault.
5)Final proof on Pariston
You know what's odd about Pariston/Sheila? Except the part that he and Pika NEVER met after the Kurta massacre(when he was Sheila)(smart Togashi!)-The panel where he said to Ging that "He loves destroying those he loves/is fond of".
Well wouldn't you say he kinda got to like Pika and Pairo when they found him/her in the forest and were taking care of him/her for weeks? Hadn't those 3 spent hours conversing, sharing stories, and getting to become closer for multiple hours a day?
Do you remember the panel where Prince Tse is sitting on his sick throne of body parts?
The head in behind him is probably Pairo's. Now, why did all the Kurta have their eyes removed, except Pairo, whose head they severed whole? I rest my case.
