Abby (Real Name: Abigail Shirley) is a member of Code LTIB.
In the first days of Code LTIB, she never knew what to do, as BT Productions made it evident that Dave Madson is never coming with her. When Looney Tunes Intro Bloopers decided to introduce Wally Warner with the reboot, Abigail decides to pursue him as a love interest. However, that was when Rowley Jefferson falls in love with Abigail, giving her some love triangle complications to get past. She still has her cat and peacock allergies. In BT Productions, her allergies extend to every cat and peacock in existance, including Decimal and Vanishing Tom.
Like George Raven, Abigail prefers to be called a different name than her real name, wanting to be called "Abby" instead of "Abigail".
Abigail never got a true love interest until Wally Warner was born. That was when Rowley Jefferson appeared and started to give Wally competition.
Rowley's love for Abby came from a Diary of a Wimpy Kid storyline where he got together with Abigail Brown for a while.
