Last week's return of Jen Clark was underwhelming to say the least. Fortunately, it seemed as if the writers of 90210 read our minds on "Blood Is Thicker Than Mud" because the old Jen returned, more conniving than ever.

All it took to spark Jen's fire was a little unhealthy competition with little sis Naomi. We've always known Jen was a desperate sociopath, but I guess finding a new sugar daddy isn't just about little Jacques.

Naomi really doesn't have any family in her life, so it makes sense that she continuously falls for Jen's apologies and excuses. Despite Jen sleeping with two of her past love interests, Naomi was ready to believe her sibling when she said she would give up Preston.

To be honest, I believed Jen too.... even though every single cell in my body was screaming not to. I should've gone with my gut and the same can be said for Naomi. It will be hard for Naomi to ever give up on Jen for good because, after all, Jen is her blood. But could Preston be the straw that broke the camel's back? Was he her soulmate of the week or could he have really been more?

I'm going to say probably not. If a guy is interested in you, he generally doesn't play you against your sister. Another super desperate girl on this show? Vanessa. I'm a fan of Arielle Kebel in real life and she kicked ass on The Vampire Diaries, but damn I just want to slap her on 90210!

Once a liar, always a liar. Liam was very understanding about the fresh start thing when confronted with her multiple driver's licenses, but Liam is also pretty trusting and naive at times. Why is she so hell bent on lying to him? She's obsessed with making him a star and he really doesn't even care that much. 

Elsewhere, Adrianna has done some crazy stuff in the past, we all know this. But it really pissed me off to see Vanessa play off of Ade's past mistakes, especially when we know how hard she's been trying to change this year. Don't get me wrong, swapping Silver's meds is still unforgivable, but Vanessa doesn't even know Adrianna. What girl would willingly slam her head through a mirror just to make an impact and keep up a lie? Damn! It looks like Silver might be her next victim after she sees how close she's been getting to Liam.

I hope Vanessa is outed for being the lunatic she is. In turn, I also hope Dixon takes the music contract. We all know he's going to since he has to take a hiatus from the show for the rest of the year. Dixon deserves his big break, though. Hopefully Adrianna will see that when he tells her.

Annie's storyilne was a snoozefest. But what else is new?

Ivy's new boyfriend is annoying and I can't stop thinking about the fact that he is Officer Garrett on Pretty Little Liars and possibly a murderer. It doesn't look like he will be in the picture once Ivy finds out that Raj lied to her and is still very sick. I always did like Raj.

So what did you guys think? Was this better compared to last week or would you rather just not see Jen? Will Silver get the test? Are we ever going to see the end of Vanessa? Hit the comments!
