This past weekend, actress Stana Katic spent some time in New York City, where she reunited with former Castle co-star Ruben Santiago-Hudson.

Castle's original captain is currently directing Signature Theatre's My Children! My Africa!, an off-Broadway play about about racial issues facing the South African youth during apartheid in the 1980s.

"Real privilege watching d powerful performances in My Children! My Africa! Directed by @RSANTIAGOHUDSON Incredible 2 have met Athol Fugard," Stana gushed after the performance.

Ruben was thrilled to see his former colleague, tweeting a picture with Stana along with Grimm actor Russell Hornsby.

It's been a month of mini reunions for Ruben, who had dinner with Nathan Fillion on May 5.

Once a member of the Castle family, always a member of the Castle family. Congrats on a successful show, Ruben!
