Biography
Wallflower Blush first appears in Forgotten Friendship when Sunset Shimmer (Rebecca Shoichet) accidentally bumps into her at the end of "We've Come So Far". While Sunset believes it's the first time they've met, Wallflower tells her they met in ninth-grade English class and that she has been on the school's Yearbook Committee all year, much to Sunset's embarrassment. When Sunset and her friends leave the room with Trixie (Kathleen Barr), Wallflower is left behind in the dark after Sunset turns out the lights.

During Sunset and Trixie's investigation of Sunset's friends' memories being mysteriously erased, they discover Wallflower Blush to be the real culprit. It is revealed through Sunset's geode powers that Wallflower had gone unnoticed by her schoolmates for years and that she found the memory stone that Clover the Clever buried long ago. Resentful toward Sunset for being so popular despite how she treated everyone during freshman year, Wallflower used the Stone to erase everyone's good memories of Sunset, causing them to view her as the bully she once was.

Before Sunset and Trixie can seize the memory stone from Wallflower, she uses it to erase their memories of the past several hours. Sunset catches up with Wallflower later, and during their confrontation, Wallflower reveals what she did in front of Sunset's friends and expresses her outright hatred toward Sunset. Ignoring Sunset's pleas, Wallflower decides to use the memory stone to erase all of their high school's memories, but Sunset jumps in the way and sacrifices her own. After the memory stone is destroyed and Sunset and her friends' memories are restored, Wallflower realizes the damage her actions have caused, and she makes amends with Sunset.

Some time later, Wallflower gets some new members for her Gardening Club, and she is named "Best Gardener" in the school yearbook.
