|Episode(s)||8.21 The Great Escapist|
You soldiers, down in the garrison, at least they let you believe the lie. Upstairs, working for Naomi, working in Intelligence, we had no option but to live in the dirt. She never reset me completely. I always knew too much, I had to...I had to do my job.
– Ion, 8.21 The Great Escapist
Ion is sent by Naomi with Esper to capture Castiel and retrieve the angel tablet. Castiel had been hiding by choosing a different Biggerson's Restaurant to go to when they got close, leaving them unable to locate him. Under orders from Naomi they murder everyone in a Santa Fe Biggerson's location to lure him there, except the waitress whose eyes Ion burns out and gives the message of "You have to stop" to tell Castiel. They catch him, and Naomi arrives. Ion is sent to search every Biggerson's for the tablet unsuccessfully. When he returns Crowley shows up and shoots Castiel in the abdomen, Esper in the neck, and Ion in the shoulder with a gun loaded with bullets made from a melted down angel blade. He tries to shoot Naomi but she disappears. They teleport with Castiel to Crowley's headquarters.
Crowley reveals that he knows where the angel tablet is, that he thinks that having realized its proximity protects him from Naomi's control, Cas still has the tablet with him. Crowley reaches inside Castiel's gut and pulls out the tablet.
Crowley orders him to watch Castiel when he goes to confront Kevin Tran. Ion reflects about how the angels have been mind-controlled and memory-wiped for a long time, and it was apparent he was miserable and frustrated with the situation. Castiel digs the bullet out of his wound and catching Ion by surprise, kills him by shoving the bullet into his eye.
