One of them was Marla Sokoloff, and the other was a blonde girl named Megan Parlen. Danielle was supposed to be Megan's role, but Director David Trainer mentioned on the podcast Pod meets World that Megan couldn't deliver a certain line as Topanga so they had Marla and Danielle audition for the role.She became a series regular during Episode 8.
