Gracefully rising up to his feet, Mirage continued the song as he moved across the cell, stepping carefully around the hulking shuttlecraft's legs. Reaching through the bars, he was able to reach his guard's control panel and the codecard for his energon shackles.

The door popped open with a low buzz as his chains fell away.

Stepping free, Mirage closed the door behind him. Reapplying the chains to the guard and attaching them to the cell, conveniently relieving him of his comm as had been done to him, should give him a little more time. Thus freed, Mirage didn't stop his rite until he'd faded into invisibility and slipped out the door.
