Sarunas J. Jackson plays "Dro" on Insecure and totally confused me in person as to how I recognized him. Sometimes all my shows blend together when I see people out in public, so you can see how that might happen.
Interestingly enough, the same thing happened with his love interest on the show, Yvonne Orji, when I met her. But in both cases I'm stoked I asked for a picture. Love that show!
