Ira Blair

Ira works as the quiet, devoted aide to Dr. Susan Duncan, tending her research and her secrets with the watchful loyalty of someone who has given up his own life to serve hers. He is careful, protective, and hard to read, more comfortable in labs and shadows than in the open.

Ari Millen plays him with a stillness that contrasts sharply against the show's more volatile characters, letting small gestures carry enormous weight. Ira's devotion never announces itself; it simmers under a controlled exterior, making him a fascinating study in quiet, unwavering loyalty within a show full of betrayal.
