One of the saddest deaths in the sci-fi series The 100 had to be Finn Collins' death. Killed at the altar of love is truly the most tragic thing to happen to any lover. But to be killed by one's lover is a still more profound agony. In the second season's episode titled Spacewalker, Finn is stabbed to death by Clarke.

Does Finn come back to life?

He was resurrected by his mother, Esther, and was placed into the body of a powerful witch named Vincent Griffith. Once again, Finn worked closely with his mother, and this time in an effort to get his younger siblings to take on mortal bodies.

Does Finn ever die?

Finn's death was the deal to establish a truce between the Grounders and Sky People. While he was not killed by the grounders to their tradition, Clarke killing him was enough for a truce/alliance to stand.
