Finn The 100: His Character, His Love Interests, His Fate

The 100 (TV series) is no stranger to killing off likeable characters to deliver some real shock value. While it might provoke sharp responses from viewers such a tendency turns out to be one of the show’s most valuable and memorable storytelling styles. Among the main characters written off the series in a somewhat grossly premature fashion is Finn Collins, whose last appearance is in Season 2 Episode 8 “Spacewalker.” Find out all about Finn from the 100 here!

Finn Collins, portrayed by Thomas McDonnel, is part of the original 100 delinquents arrested for an illegal spacewalk while on The Ark. Finn and the other 99 teenagers are sent to Earth as both punishment and an experiment to see whether the planet has once again become inhabitable after a nuclear apocalypse nearly a century ago.

Series Appearances

McDonnel’s time in the series is short, lasting only a season and a half, or 23 episodes; he appears as a hallucination in a later episode and part of a flashback in another. A simple chronicle of Finn’s short yet memorable journey in The 100 is as follows.

S1 E1 – Pilot

Viewers feel familiar with Finn from The 100 simply because he is there from the very beginning. Once the Dropship lands on Earth, he volunteers to recon the Mount Weather area with Clarke Griffin. Everyone seems positively surprised with how the planet looks, but soon they discover there are enemies lurking around. Jasper takes a spear in his chest. Finn, Clarke and the others quickly take cover.

Murphy and his followers are hunting down Charlotte and corner her on top of a cliff. The little girl ends up committing suicide. Bellamy banishes Murphy from the camp. Before returning to the Dropship, Finn gives his knife to Murphy to help him survive the wild. Finn and Clarke come back to the buried house and have sex.

Finn and Clarke make their way to camp the next morning. An escape pod from The Ark lands on an area near the Dropship. Inside the escape pod is Finn’s girlfriend, Raven.

S2 E8 – Spacewalker

In a flashback, it is revealed that Finn and Raven had a strong relationship with The Ark; Finn was only arrested because he took the blame for an illegal spacewalk that Raven did. Clarke, Bellamy, and even Kane try to find ways to save Finn from execution by the Grounders, but all plans are fruitless because Finn eventually turns himself in. In desperation, Clarke tries to convince Lexa to give some sort of clemency, but Lexa refuses anyway. Still, Clarke asks for a chance to say goodbye to Finn. She approaches him, gives him a kiss, and stabs him in secret as an act of mercy, saving him from being tortured to death by the Grounders.

More Appearances

After the event in Spacewalker, the series features McDonnel as Finn in two more episodes, including S2 E9 “Remember Me” as a hallucination haunting Clarke and S6 E7 “Nevermind” in a flashback.


We think Finn Collins is naturally contradictory and flawed. Finn goes from a lover to a cheater, and from a peaceful soul to a brutal murderer within a very short period. Everyone has a breaking point, unlike Clarke Griffin who has always been trying to be the hero of the greater good regardless of how dire the situation might be, which makes her the hero. On the other hand, Finn cannot hold his grudges after witnessing many other delinquents being brutally slaughtered by the Grounders and when dealing with the real possibility of losing Clarke. In S2 E5 “Spacewalker,” Finn reaches the point of no return as he kills 18 unarmed Grounders. With all his shortcomings, confusion, and moral ambiguity, Finn Collins possibly is one of the most realistic characters in the series.

Do you think Finn Collins’ massacre is justifiable? Does he deserve a better fate in the series? We’d love to hear from you.

Other things you might want to know:

Is there any off-screen reason behind Finn’s death?

In an interview with Entertainment Online, showrunner Jason Rothenberg says that Finn’s demise has long been part of the plan. The character has to die in the same episode where viewers seem to sympathize with him most. S2 E8 “Spacewalker” appears to be the right time to do it.
