Lindy Gertrude Watson is the primary protagonist of I Didn't Do It. Lindy is a straight 'A' student. Her best friends, Jasmine and Delia, help her keep being grounded .[ She is the older fraternal twin sister of Logan Watson. Lindy is portrayed by Olivia Holt. Lindy grew up geeky, nerdy, an outcast and on the athletic side. She is also one upper and gets excited about almost everything. Book-smart Lindy is the quick thinker of the group and known to save the day when the group finds themselves in a pinch! In Season 2, Lindy has grown up but is slightly the same as she was in Season 1. It has been shown in a couple of episodes of the season that Lindy has a habit - saying "Thats how we do things in the theatre!" - in Logan Finds Out! and Drum Beats, Heart Beats. Lindy shows a much more caring side to her in the second season with her friends as she always helps them out in situations or when they are hurt. Examples of this are in Dog Date Afternoon!, when Lindy helped Delia when she was worried about Brandon noting liking her, when Lindy helped Jasmine in Logan Finds Out!, after she was heartbroken, almost broke down and almost cried over Logan, and Lindy helped Logan in Falling for... Who?, when he was really heartbroken and cried over Jasmine after losing her to Owen, which showed how much Lindy has changed and is very caring towards her friends. Also in Season 2, Lindy is shown to have become more confident around boys as she has dated two in this season - Jake and Scott - showing she isn't shy around guys as much as she appeared to be a little in the first season.
