The conversation between human and AI assistant.
Why was Jaqen H'ghar captured in the first place with the other two prisoners if he has such skills?
Oh, I see. Did Jaqen have any other important missions throughout the series?
Yes, he became a mentor of sorts to Arya Stark and helped her develop her assassin skills. He also played a key role in the events that led to the fall of House Frey and Arya's revenge against Walder Frey.
