Spoilers for Orange is the New Black season two...
In "It was the Change" (episode 12), the conflict between Red and Vee intensifies:
Red tries to strangle Vee but can't bring herself to finish. The next day, in retaliation, Vee viciously beats Red in the greenhouse.
Soon into the next episode, we learn more:
Red is recovering in the infirmary, sore but with no permanent damage. Suzanne is framed for the beating and likely to be found responsible.
This outcome seems out of character for one of them. What I wonder is:
Why would Vee allow Red to live? Red interpreted the beating as a warning to silence her, as well as a punishment, but killing her would have served both ends with no risk of exposure or retaliation. Vee had the capacity and the means to kill, no witnesses, and a scapegoat to take the fall for the murder. As evil as she was, and as tactically calculating as she was in her criminal schemes, why would she allow an enemy like Red to live when she could simply eliminate her?
The real-world explanation is that Kate Mulgrew is one of the stars of the show and they don't want to lose her. But I'm hopeful for an in-universe answer that makes sense given Vee's nature and the situation.
