Her injury along with Oompa's fatal wounds made Flintstone start to turn on Ben for his leadership decisions. She was shot when they made a break for it but was safely brought to a outlet store to recover. Ben/Zombie set a bomb to blow and give them so cover and had Teacup run with the rest. The assignment went south when the squad was pinned down and had to take cover behind a diesel truck. When the squad was given their first combat assignment, Teacup was ready to go. When Ringer came into the squad she was impressed with her tough exterior and feminist attitude. She was there to witness when Tank had gone Dorothy and pulled his gun out on all of them when he started raving about the Others. Teacup was the youngest member of Squad 53 until Sam/Nugget had arrived. She has appeared in The 5th Wave and in The Infinite Sea. She ultimately met her end when she was shot by Razor to eliminate her as leverage to be used against Ringer. She was thought of as disturbing by Cassie Sullivan who thought it bizarre that a young girl like her could stroke an automatic rifle so fondly. Eventually little cracks become visible in the breakable Teacup. Teacup's vulnerability is seen as important survivors of the waves are overcome and she becomes unsure of who she can trust. She is unafraid to take risks and seems oblivious to danger but her humanity is evident in the battle-scars she receives during the Fifth Wave.

Initially she hero-worships Reznik but later she develops a tight bond with Ringer, the newest member of Squad 53 who joined after Tank went Dorothy.

She is jealous of Nugget/ Sam Sullivan who replaced her role as the adorable, cussing baby of the squad.

Teacup is described to be the meanest 7 year old that you'll ever meet. Human Teacup is a survivor of the ' waves' and was originally the only female member of Squad 53.
