The faceless man in GOT is one of the most mysterious , dangerous and dynamic character in GOT ,he is loved by everyone He was the mentor to arya stark , he taught us how to swap faces and kill like a cheetah.

Jaqen H'ghar is part of Yoren's group ofrecruits taken from King's Landing to join the Night's Watch in the North.He is taken from the Black Cells with two other prisoners; Rorge and Biter.

He tries to talk to Arya while being escorted to the wall, but she manages to avoid him, until they get attacked by ser Amory Lorch and his company. They kill Yoren and set the barn where Jaqen and his companions in on fire. But Arya gives Jaqen an axe to set them free before she escapes.

At Harrenhal, Arya meets Jaqen again when he becomes a member of the Lannister men. There, he tells her that he owes her three deaths in exchange for her saving him, Rorge, and Biter. She uses him to kill two of her enemies; Chiswyck and Weese. But for her third victim, she threatens to name Jaqen himself, unless he help her free Roose Bolton and the North Men so that they can take over Harrenhal.

Once his promise is filled, Jaqen H'ghar reveals his faceless nature to her, gives her an old iron coin, and tells her that she can find him by giving the coin to any man from Braavos, and say the words valar morghulis. Then he announces that "Jaqen H'ghar" must die, and passes a hand over his face, making it magically reshape into a hook-nosed man with a gold tooth..Though his role was not justified at the end of the show but still his character and the scenes were a thrill to watch ,this where the prime days of GOT

The most favourate scene of mine in the entire show is when arya stark tells jaqen that

“the girl is arya stark of winterfell and I am going Home “followed by the music
