So what was he doing?

When Robert stops the van and grabs the wife out and takes her to the back what is going on? Is he raping her? Or beating her up?

*UPDATE*

OK I see someone has asked this and someone replied he raped her b/c she mentioned the rape, but I thought Jeff was the one who raped that she was talking about.

Most people see things that are and ask "why?", I dream things that never were and ask, "why not?"
