Season 1
Jaqen H'Ghar is in the party led by Yoren that leaves King's Landing for the Wall, along with Hot Pie, Lommy Greenhands and Gendry. Jaqen is not identified, as the actor had not been cast at this point. However, speculation is that he is the cloaked and hooded figure in the wagon.

In the books
In the Song of Ice and Fire novels Jaqen claims to be a citizen of the remote Free City of Lorath. However, whether this is true or not is unknown.
