Season 1
Ser Jaremy attends the induction of new recruits into the Night's Watch.

He leads an escort for Jon Snow and Samwell Tarly when they go north of the Wall to take their vows in the Godswood. He embraces his newly sworn brothers after they take their vows.

In the books
In the Song of Ice and Fire novels, Ser Jaremy is an officer in the rangers of the Night's Watch. Ser Jaremy attends the officers meeting with Tyrion Lannister and recalls being sent to the Wall by Tywin Lannister after fighting for House Targaryen against the House Lannister in the Sack of King's Landing during Robert's Rebellion. It is Ser Jaremy rather than Ser Alliser who challenges Sam about his decision to take his vows in the Godswood. He is not named as being part of the escort to the Godswood. He identifies the bodies when they are returned to Castle Black. He is killed by the wight Jafer Flowers in Castle Black in A Game of Thrones.
