In November 2019, it was announced that Teressa Liane had been cast in the role of Mimi for the digital series "Last Blast Reunion".

[8] Mimi's childhood was marred by the abusive behaviour of her father, David, which not only affected her but also led to her brother Patrick leaving the home.

Jan preyed on Mimi's insecurities and used them to torment Chloe, including taking naked pictures of her in the shower.

Mimi then developed a crush on Shawn-Douglas Brady (Jason Cook, later Brandon Beemer), but he was interested in Belle.

The prank almost put Mimi in jail, but instead, she is forced to spend her senior year at Salem High cleaning bathrooms as her punishment.

Mimi's friends start to notice her odd behavior, which includes staying away from them and roaming the streets at night.

Mimi eventually gets together with Rex Brady (Eric Winter) but fears he might be the Salem Stalker: the serial killer who had supposedly killed several residents, including Rex's sister, Cassie Brady (Alexis Thorpe) (eventually, it is revealed that all of the victims, including Cassie, are alive).

Jan returns to Salem, and Mimi learns she has been keeping Shawn hostage at her country home.

Jan trips and hits her head on a rock while arguing with Mimi and ends up in a serious condition in the hospital.

Mimi's guilt over her lies to Rex starts to get unbearable, but her mother, Bonnie Lockhart (Judi Evans), convinces her to keep quiet and hold on to her man.

They decide to ask a surrogate to carry their child, but a mix-up in the lab causes Mimi's egg to be fertilized with Philip's sperm and Belle's egg with Shawn's sperm; the EJ DiMera is responsible for this mix-up as part of his crusade to ruin the lives of the people in Salem.

Mimi briefly works at Chez Rouge but leaves after a fight with Shawn's girlfriend, Willow Stark.

Victor Kiriakis's goons hold them hostage in a church basement where they share their first kiss and also discover a skeleton.

Bonnie explains that Mimi killed her father but suppressed the memories because David used to abuse the family.
