Anwen O’Driscoll as Riri

Riri is Arkadi Timurov, a business tycoon and a criminal’s younger daughter in Bet. Played by Anwen O’Driscoll, Riri is the half-sister of Kira, and with her minimal dialogue and conflicted personality, she has left a mark on the story.

She is loyal to Kira and speaks very little while wearing a mask and conveying most of her emotions and feelings through her eyes, a trait that makes the character even more interesting.

Anwen O’Driscoll has previously acted in October Faction, This Time, You Can Live Forever, etc.

Clara Alexandrova as Kira

Played by Clara Alexandrova, Kira is Arkadi Timurov’s eldest daughter and the president of St. Dominic’s student council in Bet. She shares a number of character traits with her father, and unfortunately, none of them are positive.

Like Arkadi, Kira is also a megalomaniac and believes in exploiting people to get her own work done. She is ambitious and power hungry, and between her and her younger sister Riri, she is shown to be seeking validation a lot more than her, which fuels her actions and decisions throughout the show.

Clara Alexandrova has previously been seen in Danger in the Dorm, A Million Little Things, Alert: Missing Persons Unit, etc.

Aviva Mongillo as Dori

Aviva Mongillo plays Dori in Bet, a character who is impulsive and nerdy and does not have any idea about social connections. While she comes from a privileged background, her lack of social skills turns her into a stalker, and given her troubled relationship with her father, her character embodies all the negative qualities a teenager with lots of money and zero moral compass can have.

Aviva Mongillo has previously been part of projects like Workin' Moms, Backstage, etc.
