DEAN RUSHES HOME TO CHECK ON LISA --- Ben calls Dean and tells him Lisa is in trouble. Dean leaves Sam to investigate a case alone and rushes home to rescue Lisa, however, he’s not prepared for what meets him at the door. Meanwhile, Sam discovers the men that were murdered were all a part of a cruel practical joke played on a female co-worker who went missing.

I think Ben's going to find out that Lisa's going on a date with another guy and call Dean and lie and say she's in trouble so Dean will rush back and, in Ben's mind, get back together.
