Suspicion

Finally, some "analyst" has now come around to my theory that the escapees never intended to take off with the woman who helped them escape, and that they'd arranged for someone else to pick them up.  Moreover, I think it more than likely that clueless Joyce may have gone to the pickup site to find them already gone, and THEN checked herself into the hospital. The chest does hurt when the heart is broken.  And besides, she knew they were open to murdering anyone who could block their plans. Oh, the pain!
