The 100 left Abby (Paige Turco) in a very precarious position last week, completely at the mercy of McCreary (William Miller) and his band of misfits, who had taken over the prison ship's camp.

Given that she's the only person on the planet who knows how to cure them of their lung disease, we'd hoped Abby would at least be treated civilly, but that just doesn't appear to be the case. In this exclusive sneak peek at this week's episode, McCreary is using what could be his very last breaths to threaten Abby into helping him.

Even though she puts up a good front, it's obvious Abby is hurting without her pills, and she's proven unreliable in resisting her addiction up until now. When push comes to shove, will Abby be able to stick to her guns, or will she end up caving under the weight of her withdrawal?

With Octavia's (Marie Avgeropoulos) army on the way, the prisoners' camp in disarray, and almost every alliance worth preserving broken, The 100's fifth season seems to be coming to a tense (and potentially cataclysmic) head.

The 100 airs Tuesdays at 8/7c on The CW.
