'Pretty Little Liars': Melissa's return, Kate's first day at Rosewood High

kate-PLL.jpgA couple familiar faces are popping back up in Rosewood on "Pretty Little Liars." First, on the Monday, Jan. 30 episode, Hanna's evil stepsister is back in town and starting school at Rosewood High. And she doesn't even have her friends to turn to, because Aria, Spencer and Emily are kind of giving her the cold shoulder.

What Hanna doesn't know, of course, is that it's because they went behind her back to keep working with Caleb. We're sure she'll be thrilled to find out.

And then on the Monday, Feb. 20 episode - Melissa's back and she's very pregnant. The episode description for "Breaking the Code" says that "a surprising new victim of 'A' is revealed ... the PLLs tight-knit group may just get one person larger."

Is it Melissa? We wonder. "Pretty Little Liars" airs Monday nights at 8 p.m. ET/PT on ABC Family.
