In the new TV Guide's pratonton of returning fall shows, the blurb for Lie to Me mentions that Cal will discover Emily has been drinking and sexually active, and there will be all kinds of issues with him having to deal with it.

Sounds to me like there will be ALOT to deal with this season.
Personally, I think that they should have left these kind of 'typical' teenage issues out of Emily's character and out of the SHOW...but I guess we'll have to see how it plays out.

I mean, Cal is a protective father, now just imagine him discovering this from his daughter...O.o

He's going to beat himelf up about it, and (Dare I say it) even HER if this goes to far. But THAT situation ever unfolding is FAR beyond Cal's character.
