Aside from any questions regarding loyalty or ethics, O’Keefe wants very much to find out what Shaver has told Striper of his plans. She’ll certainly have told Striper something, possibly everything. Striper has experience with interrogations, O’Keefe assumes, and in her current frame of mind she will probably be quite brutal, not unlike an animal. The only real question is whether or not Striper will leave Shaver alive. O’Keefe has doubts in that regard.
