Not much of a scandal considering what we've seen the last few seasons. It's not nearly as scandalous as Ed having two girlfriends back home and Jill still choosing him as her F1. I'm glad Ali will have the good sense to kick the guy to the curb immediately.
Could they somehow use Jake to come back and tell Ali about the g/f? It certainly wouldn't be out of character for him since he blew the whistle on Jill's season. Maybe he comes to tell Ali before she actually gets the phone call from the g/f. They could use Jake for dramatic effect. Ali might originally think he is back for her and some viewers could believe that as well?? Just a thought.
