Bo rescued her and while filming location scenes at Duke University, Sarah realized Neil was indeed the killer, so Neil stopped Sarah from escaping and chloroformed her as she cried out for Bo. He then dragged her to the University clock tower where he held Sarah captive.
Mari-Lynn, Wade and Bo located Neil and Sarah and burst into the tower to rescue Sarah. Neil had an axe to defend himself with and pushed Wade over a railing as Mari-Lynn hovered over Neil in tears.
