- "No! Not the vase!"
- — Matilda
She has a light purple hoodie and a green jacket from her counterpart of Matt, a light purple comb-like ribbon tied and orange, straight hair.
- As Dazeem smashes a nearby vase Matilda yells "No! Not the vase!" as reference to Matt in "Space Face" parts 1 and 2 (Part 1 being a flashback/foreshadow of the final moments and in Part 2 yelling "No! Not the face!").
- She can also be seen in the background in a picture frame in Matt's new room in "The End (Part 2)".
