In the Scorpion episode “US vs. UN vs. UK,” while Sylvester (Ari Stidham) takes a bold step to protect Megan’s (Camille Guaty) wishes, the team is blackmailed to break into the United Nations and to help assassinate ambassador Jonas Madaky — who it turns out is also a dangerous arms dealer. The team’s challenge involves British Agent Olivia Cromwell.
Olivia Cromwell is portrayed by Sonya Walger. She’s known for her roles on the new show The Catch (con artist Margot Bishop), Criminal Minds: Beyond Borders (Former MI-6 Agent Marion Codwell), Power (Madeline Stern), Scandal (Katherine Winslow), Parenthood (Meredith Peet), Lost (Penny Widmore), Terminator: The Sarah Connor Chronicles (Michelle Dixon), CSI: NY (Jane Parsons), and The Mind of the Married Man (Donna Barnes), among others. Scorpion airs Mondays at 9pm on CBS.
