The Grounder's most deadly saying will take center stage in The 100's season 2 finale.

Sky People To Pull A 'Heist' On 'The 100', Jason Rothenberg Teases Finale & Attack On Mount Weather

Titled "Blood Must Have Blood: Part 1 & 2," the last two episodes of the season will pack in as many heart wrenching decisions as possible. Set to air in the wake of "Bodyguard of Lies," the penultimate episode will focus on all three fronts of the current battle - the Sky Teens in Mount Weather, the Grounder/Sky People alliance, and Jaha's (Isaiah Washington) quest for the City of Light.

Clarke (Eliza Taylor) and Lexa (Alycia Debnam Carey) will prepare to lead their respective factions into battle against Mount Weather while turmoil continues to be the norm inside the rock-solid fortress. As Bellamy (Bob Morley) works to keep his word to someone, President Cage Wallace (Johnny Whitworth) will reveal some new information. Meanwhile, Jasper and Maya will see something "horrible," according to The CW.
