Patty Schwab is Carly's alias in iParty with Victorious. Her make-up is done by Spencer's ex-girlfriend, Moni. When Steven came up to Carly at Kenan Thompson's Beach House, Carly faked a British accent to fool him so he wouldn't notice her. When Carly saw Tori and Steven talking and preparing for their "100 Day Kiss", Carly, Sam, and Freddie peel all of their make-up off of their faces, thus making them look like their normal selves.
The last name, Schwab, could possibly be a reference to Stacey Dillsen, a character in Zoey 101 who had a lisp, and was obsessed with cotton swabs and white glue.
