Wife Swap (8:00 p.m. EST, ABC)

This one is sure to have tons of drama. One family is super competitive and plays hockey. The other? Oh, they’re just some Goths who commune with the dead and dance ballet. So how will they react when the wives swap places? Watch and see.

Medium (9:00 p.m. EST, CBS)

On tonight’s episode, Allison (Patricia Arquette) reacts to her neighbor’s murder by installing a hi-tech home-security system. However, she then realizes that the alarm system is communicating with Marie (Miranda Carabello). I’m most curious about how the security system communicates with a child. Does it talk out loud, or does it communicate in a series of bleeps and boops? Elsewhere, Ariel (Sofia Vassilieva) comes into contact with a ghost who may be able to help her get into the college she most hopes to attend.
