Missy Robinson

Missy Robinson is Carly's former long-lost best friend. She is portrayed by Haley Ramm, the real-life best friend of Miranda Cosgrove. Missy adores Carly but loathes Sam and plots several ways to get Sam out of Carly's life to remain Carly's best friend. Based on behavior, she is also similar to Valerie. It hasn't yet been confirmed if Missy will make another appearance in Season 4, because it was said to be "a six month cruise." Dan Schneider rarely creates characters that stick around or have an effect on a character's life, so she may never appear again at all.

Early life
Missy met Carly when their families were stationed at the same naval base at Seal Beach. They eventually grew apart when Missy left Seattle.

When Missy returned to Seattle, she caused a rift to develop within Carly and Sam's friendship. Sam noticed that Missy intentionally gives her a fake address that led her to a factory that makes piñatas (with no candy inside of them, to her dismay) instead of to the skydiving port, then drops her phone in Wahoo Punch. To "make up" for these events, Missy gave Sam Persian chocolates, but the candy expired in 1992, giving Sam a "stomach bomb" and food poisoning. Carly believed that all of these events were coincidences, refusing to think that Missy would hurt her friend, and convinced Sam that she was acting paranoid. Carly tried to play peacemaker, and called them all together at the Groovy Smoothie to settle their differences. Missy and Sam apologized to each other, but once Carly left to buy smoothies, Missy showed her true colors and admits that Sam was right, she was trying to sabotage Sam so she could be Carly's only best friend; causing Sam to have a "defected cup". She knew Sam wouldn't retaliate in fear of losing Carly's friendship and used this to her advantage.

Freddie won a contest for the six month "School at Sea" program and gave the trip away to Missy. When she gloated about this to Sam, saying it's no longer necessary to be Carly's best friend, Carly was right behind her, and found out that Sam was telling the truth. Carly stated that Sam is her only best friend, and Missy told the girls to "enjoy each other" while she goes on her trip. Carly reveals that Missy used to get seasick, and bets that now she isn't. The end scene shows that Missy is indeed still sea sick, and the ship she rides turns out to be a freightet.

FUN FACTS: Haley Ramm and Miranda Cosgrove acted in the movie "Yours, Mine, and Ours" together, which is probably how they first met.

Haley and Miranda are best friends in real life.
