Mallory was always treated like a child and was always watched by her guards, as well as made to wear princess dresses. On the night of a masquerade she decided to escape the embassy and go see the city. She watched a couple street performers until noticing a televised news report claiming she had been kidnapped. She was shocked to think she had caused a scandal when she simply wanted to see the outside world, and hailed a cab to return to the embassy.
Her guards were just about to arrest the TMNT for kidnapping until she intervened and told them that she wasn't kidnapped. At this point, Leonardo and Donatello pointed out that she looks so much like their friend April, that Shredder must have kidnapped her instead. The Turtles saved April and Mallory returned to her father. Later, she appeared with a platoon of her guards at the museum when Shredder had the Turtles cornered. Realizing he was outnumbered, Shredder fled.
