Diyah Pera/The CWThe 100 fans know that the CW's hit post-apocalyptic drama is a great show to binge-watch. You can easily breeze through season one in less than a day. (Full disclosure: we've done that...multiple times. No shame!)
But you're not going to want to wait to watch tonight's midseason finale.
In fact, even the series' star Eliza Taylor is warning you to watch the episode live. Because you're not going to want to be spoiled. Trust us. Not. At. All.
"Listen, this is an episode fans are going to want to watch live," Taylor tells E! Online. "I'm excited for fans to see us go to a really deep level. I think we're going to really be exploring some serious emotion and heavy stuff."
Now that the Commander of the Grounders has told Clarke (Taylor) that the only way the people of the Ark will achieve a truce with the Grounders is if the Ark hands over Finn (Thomas McDonell), all hell is about to break loose at Camp Jaha.
"There's going to be a lot of mixed reactions from the camp," Taylor says. "Obviously, no one wants to see one of their own die by the hands of the Grounders. But at the same time, a lot of them—if it means their survival—are going to want to turn him in. There's going to be a lot of conflict within the Ark about this."
And how does Clarke feel knowing she's about to deliver the news that a death sentence for the man she loves is the only way to end the war?
"It's absolutely heartbreaking for her," Taylor says. "Clarke is in love with him and has been since the very beginning. The thought of losing him is, well, it's just not an option for her at this point."
But just because she's in love with him doesn't mean she's fully pardoned him for his crimes (namely massacring an entire village of peaceful Grounders) like the rest of her people have already.
"It's very unsettling for her to realize what he did in her name," Taylor says. "I don't think she'll ever fully understand it. But at the same time, they've all done such crazy things to survive and sometimes that means they've done the wrong thing. There is a level of understanding there and seeing how vulnerable and how much Finn is punishing himself, she's forgiving him herself."
Does she blame herself for what happened to that village, since he was only there because he thought she was being held captive there?
"I think there's definitely a level of guilt with what happened, especially after realizing that he was doing it all to find her," Taylor says. "But I think she can't really blame anyone but him. It was all him."
If the Ark does hand Finn over to the Grounders, Taylor reveals that there won't be a happy ending for him.
"The Commander wants to see him sacrificed in a really brutal way," Taylor teases, "because it's the only way to bring any sort of justice for the village he massacred. It's their tradition."
And while we won't reveal whether or not the Ark hands Finn over to be sacrificed or if he makes it through the hour alive, we can reveal that the way Clarke figures out a solution to the whole issue is incredibly impressive (as is everything she does, because Clarke is a damn boss). Yes, shippers are going to have mixed reactions based on personal preferences, but no matter who you're rooting for, it will change everything going forward for both the Grounders and the people of the Ark. Seriously, this show will never be the same again.
As a stark contrast to the major choice Clarke and the others from the Ark are facing, another storyline that is going to play out in "Spacewalker" is a flashback to earlier, happier times on the Ark.
"We're going to see a lot of flashbacks to Finn's journey which I think is really cool," Taylor says. "You're going to see young Finn and Raven [Lindsey Morgan] before he got arrested. It's going to give you a really cool insight into his past and the kind of person he is and his relationship with Raven. I'm excited to see a glimpse into life back on the Ark again."
Prepare yourselves for a roller coaster ride of emotions, The 100 fans. There are going to be really high highs, and brilliantly devastating low lows. Don't say we didn't warn you.
The 100 midseason finale airs tonight at 9 p.m. on the CW.
