In Bloggers & Butterflies, Tilly hates on Austin and posts embarrassing photos and videos of him on her blog. She later shuts it down after she accidently admits, on the stage in which Austin performs The Butterfly Song, that she was the one whom was running the blog and spreading bad rumors about Austin.

Tilly also admits that she doesn't hate Austin. She just had hated Ally because they went kindergarten together. The kindergarten class were doing an insect-themed spring pageant and the kindergartens had to choose the best song for the play. The class chose Ally's, and ever since Tilly had hated Ally.
