Spencer's evil sister Stephanie shows up and causes all kinds of chaos this week. First, she offers to marry Spencer and Heidi, as she is an ordained minister via the internet, but Heidi puts the kibosh on that idea in a hurry. Later, at Opera (that's a club), Lauren and the gang hang with Brody and Frankie, when Brody spots Stephanie. She makes a beeline for the table where she accused Brody of hanging with the enemy. Then Stephanie's drunk friend tells Lauren to stop messing with Heidi. Brody sticks up for his peeps and tells the "She-Pratt" to mind her own business.

Audrina complains that Justin-Bobby isn't attentive enough -- especially when he's staring down other girls. He actually gets up from his table with Audrina, picks up another girl and kisses her -- right in front of everyone. The girls storm out and Justin walks out after, hanging on the other girl! Justin follows Audrina and total works her over. He says all the things the scum bag boys say, so that you'll forgive them. Audrina buys it all and goes home with him -- leaving Lauren in the parking lot. So wrong.

I HATE JUSTIN BOBBY!

Stephanie reports back to Heidi and Spencer about her showdown with the enemy, and Heidi looks like she wants to crawl into the cabinet, while Spencer and Steph gloat like they've actually done something to be proud of.

Audrina tells a co-worker about her night with Justin and says she dumped him after they drove away. She vows to really, really end it later, when he comes over. At the apartment, Justin shows up looking clean and cute (though it pains me to say that). He tries to convince her that she imagined him kissing that other girl. Audrina manages to stand her ground and give him the 'lets just be friends" line. She cries when he leaves but, we all know, she's so much better off without him.

Next week: Another Heidi/Spencer fight and more flirtation between Brody and Lauren.
