Charlotte

Charlotte was initially a classmate of Taylor Hebert. She was among the many who witnessed Sophia forcing her into the locker, but kept quiet about it (it's implied that she feared Emma Barnes). When Leviathan struck her family couldn't evacuate and stayed behind. Charlotte ended up getting captured by the Merchants. During her attempt to rescue Bryce Taylor saw her on display and in a moment of pity persuaded Lisa to order one of her soldiers Minor to free her. Charlotte was grateful, but recognized Taylor as "the locker girl" before going into detail about what happened. Skitter became enraged but decided to let Charlotte come along. When the Merchant event devolved into a brawl, she witnessed Skitter and Tattletale relive their trigger events, and started to become suspicious. After seeing Taylor demonstrate her powers to Newter, her suspicions were confirmed.

At Tattletale's hideout Charlotte was recruited by Taylor, and became the second of Taylor's recruits before becoming one of her top lieutenants.
