Fynn

Fynn was a former Glader who's name was seen engraved on the wall. His name was not crossed out at the time, which meant he was alive at the time when Thomas arrived. He is only seen once in the film when he is following Thomas and the other Gladers during the Griever massacre. He was then tackled by a Griever and killed. He also seen at the Celebration when Alby puts his arm on Fynn.
