Samwell Tarly
A.K.A: Sam, Sam the Slayer
Age at the start of season 8: 25 years old
First appearance: S1, E4 “Cripples, Bastards, and Broken Things”
Best moment: When Sam killed a White Walker, thus helping to determine how to kill them in the first place.
Worst moment: Cleaning the chamber pots of all the sick maesters in the Citadel.
Where he/she is at the end of season 7: After arriving at Winterfell, Brand reveals to him that Jon is actually the son of Rhaegar and Lyanna, but Sam remembers Gilly reading aloud about the secret annulment of Rhaegar and Elia Martell, and secret marriage of Rhaegar and Lyanna, making Jon the true heir to the Iron Throne.
Season 8 bold prediction: Sam is going to be the one that retells the story of the Great War in Oldtown and will record how to defeat the Nigh Walkers in case they come back. I think he and Gilly will live happily ever and have a brood of their own. Wait, can maesters get married?
