Things got even more complicated on 'Life Unexpected' (Mon., 8PM ET on The CW), when Lux confronted Cate about giving her up for adoption.

And her words cut deep: "Now doesn't count," said Lux. "I'm sorry, I don't forgive you, Cate. I don't know when I'll ever be able to forgive you."

Well, she'll have to get in line because Cate said she won't be able to forgive herself either. Let's hope someone forgives someone on this show eventually.

It's your worst nightmare. You're about to, having, or just had sex with your boyfriend, and your parents come over to give you the sex talk.

Poor Lux on 'Life Unexpected' (Mon., 8PM ET on The CW). Poor Lux's parents. Poor Lux's boyfriend, hiding behind the bed while the sex talk is taking place.

These days, it seems as if practically every teenage character on TV is wealthy, witty and dressed like a fashion plate -- basically, a mini-adult for whom parents and school are just an inconvenient distraction.

That's why Lux, the character Britt Robertson plays on the CW's 'Life Unexpected,' is such a breath of fresh air on the teen drama landscape. Having grown up in foster care, 16-year-old Lux tracks down her birth parents so that she can be legally emancipated, only to find herself stuck with them (and vice versa). Her birth mom, Cate Cassidy (Shiri Appleby), is a radio host who's romantically involved with co-host Ryan Thomas (Kerr Smith); her dad is bar owner Nate "Baze" Bazile (Kristoffer Polaha), a lifelong slacker who's forced to grow up right along with Lux.

As Lux, Robertson -- at 19 already a showbiz veteran, with credits that include 'Dan in Real Life' and 'Swingtown' -- gives a charming, unpretentious, totally relatable performance, which is one of the many reasons 'Life Unexpected' (which has been compared to family dramas like 'Gilmore Girls' and 'Everwood') is one of the best midseason shows of 2010. We spoke with Robertson from her home in L.A. about where both she and Lux are headed in the future.

(S01E07) Perhaps this episode should have been called 'Comeuppance Received'? Tensions between Cate, Ryan and Baze boiled over and for once, Cate is the one who messed up royally. I've said before that it's been hard for me to connect with Cate and see past her grating Type-A exterior. But even I winced at the epic dumping she got from Eric. It was deserved, but brutal.

And Cate's early attempt to whitewash her whole affair looked even more petty in wake of the serious drama Lux was going through with Tasha. The kid had a tough time this episode, and sadly, only Baze was really there for her in the end.

(S01E04) I am so excited for the return of the infamous bong lamp, but wow, does it cause some major trouble. Last week, we saw Lux sell Baze's pride and joy to help cover his bar rent. Two weeks ago, the offending lamp was also one of the reasons Baze was denied full custody of Lux. This week, it's the reason she gets suspended from her fancy-pants public school. Stupid lamp, can't do anything right.

We're ratcheting up the drama here this week. Lux's illusions of family life crumble a bit more as she and Cate, in the grand traditions of mothers and daughters everywhere, clash something awful.
