Trouble brews for the gang when Marissa's younger sister, Kaitlin Cooper (whom is even more devious and amoral then Julie), arrives in Newport for a visit from her Montecito boarding school. Julie is finally forced to tell the truth about her living condition to Kaitlin and Marissa. Within a matter of hours, Kaitlin has hit upon Johnny and tries to get him and Marissa together despite knowing that she's still dating Ryan. Soon, some of Kaitlin's problems follow her to Newport involving her drug-dealing boyfriend Justin, and she fibs a lot to Ryan and Marissa about her problems. Meanwhile, Kirsten and Julie decide to start their own dating service, but the evil Veronica Townsend brings more trouble when she blackmails them to get her up on a date with Summer's father. Johnny, frustrated that he will not be able to go on a surfing tour, beings to distance himself from Marissa. Written by Anonymous

The Sister Act (#3.12)
20 September 2014 | by (Canada) – See all my reviews

Kaitlin Cooper came back from the boarding school for vacation. Julie has to explain to her that they now live in a trailer. Marissa feels bad for losing connection with her and also wants to be friends again with Johnny as she finds out the truth about him. A guy comes from Kaitlin's past as she stole his friend's money and dated him while lying about her age. Now she is hitting on Johnny. Taylor's mom tried to date Summer's dad but this got prevented as Julie has feelings for him too.

Well, I already forgot that Kaitlin exists. And now she is back being a little brat. Really went after her mother. Although I love Julie and can't say that yet about Kaitlin. Her first scene talking to Ryan was pretty funny though. But I already feel bad for Johnny.

Julie and Summer's dad getting together, now that would mean Summer and Marissa are sisters! Somehow I feel this will work out as this is something the show producers would like.
