My name is SoCalGirl and I watch Disney preteen/teen tv!
I was totally watching Sister Sister tonight too. I'd seen it before I pledged SK and never realized that they used actual names. (AKA, Delta, APhiA, and Kappa Alpha Psi) p.s. There was a SGRho in the crowd but I didn't spot any Zetas.
While I feel over all it's not a negative episode, I still feel the same way after I first saw it. I wanted to grab Jordan by the ear and scream "YOU AIN'T NEVER GOING TO BE A GOOD REPORTER IF YOU'RE BLIND TO WHAT'S RIGHT IN FRONT OF YOUR EYES!!!!" You go looking for hazing and you find you're forced to dress identically to your line bros, you're forced to march in formation, you can't talk to anyone but the bros and the Gamma Pearls, and you're deprived of sleep so that you can clean a campus quad until 8am.

But since they didn't put the beat down on you, you weren't hazed.
Did anyone notice in the scene w/ the lil old ladies, one of the brothers in the background had on a white shirt that had the gamma on his left instead of the right. Was the costume designer not paying attention. With Gamma Psi you have a 50/50 chance of gettin' it right!
