No strings attatched?

Hilarious episode last night. Now that the that divorce is fully underway, Sam and Cindy are trying to get the kids to pick sides. (Don't forget, their two daughters Anna and Kate were adopted. Sources have said this fact will come into play sometime. Could this season be the one?)

I couldn't help laughing at how obvious they were about it. Cindy kept taking the girls on shopping trips for "bonding time," despite her constant insistence that the separation had her spiraling into depression. And Sam started acting the family man, making dinner every night. And not just dinner, but breakfast for dinner? How the girls didn't see the strings attached to their late-night waffles is beyond me.

And don't fret. There was also plenty of drama to balance it all out. Tired of being treated like the bad guy, Sam launched an investigation into Cindy's past, attempting to uncover something that would put her into hot water, too. In the episodes final minutes, he was staring open mouthed at something he'd uncovered. And then a big fat 'to be continued.'

Any guesses as to what the big discovery could be?
