The Emergency Medical Hologram aboard Rios's freighter La Sirena, a soft-spoken English-accented copy of his captain who is shut off by Agnes Jurati as she kills Bruce Maddox.
Emil is one of the five emergency holograms installed on La Sirena, all of which took on the appearance of Cristobal Rios when he accepted the ship's self-scan option. Emil is the medical programme, calm, solicitous and rather English, and like the others is played by Santiago Cabrera.
He is first seen in The End Is the Beginning, removing shrapnel from Rios's shoulder and gently needling him about his state of mind. In Stardust City Rag he activates in sickbay when he detects Agnes Jurati's distress, and she switches him off so that she can disable the equipment keeping Bruce Maddox alive.
In Broken Pieces Raffi questions all five holograms together to find out what Rios has locked away about the ibn Majid, and Emil admits that part of his memory has been removed.
