Yvette was tasked with keeping Nia from falling asleep when her roommate began struggling with "nightmares". When Nia had another "nightmare", Yvette quipped how she "[sleeps] funny". Nia told Yvette off for not doing what she asked, to which Yvette protested she allowed Nia a couple hours of rest, which is needed to stay functional at work.
During her and Nia's Valentine's Day party, Yvette forced Brainy to dance, claiming every song to be her "jam". Shortly following the party, Yvette woke Nia from yet another "nightmare" before asking her to help clean up. Later that night, she welcomed Brainy into her apartment when he arrived with a box of chocolates for Nia. She ate through them, keeping Brainy company until Nia arrived home.
During the Anti-Monitor Crisis, Yvette as well as everyone in the multiverse except for the seven Paragons, was killed in an antimatter wave by the Anti-Monitor on December 10, 2019, only to be restored a month later, after the Paragons and the Spectre created a new universe.
In the new earth, Yvette was beaten by a man named "Angus" to attack the transgender community, because Nia (under the persona of Dreamer) is transgender and was trying to get her to quit being a super-heroine; but his attempts completely backfire, as he was taken down by the superheroine, arrested and sent to prison for his crimes.
