At one point, Tree plots out a way to kill Tombs. She goes to the hospital, pulls a knife on the officer, takes his gun, tells him that Tombs is about to escape and to go get help. She then goes into his room where he escapes, they fight and she shoots and kills him. She's then seen celebrating her birthday. There is no way that she'd be free that night - she would at the very least be charged with the murder of Tombs since there's no witnesses to see that he did in fact free himself. From an outsiders point of view, she took an officers gun, untied Tombs, and then killed him. See more
