They escape, but become temporarily trapped in its cage.
Kane attempts to take his own life rather than kill Jaha, but a Grounder witness, Lexa, reveals herself to be the commander and says she believes their wish for peace is sincere.
She allows Jaha to escape with a message to his camp: leave within two days, or die.
In the end, Clarke goes to meet with Lexa in a last-ditch effort to save Finn from the brutal execution process Lincoln has explained.
When Lexa refuses clemency, Clarke asks if she can say goodbye to Finn.
She approaches, kisses him, and tells him she loves him while stabbing him in the heart, killing him quickly.
