Arglefumph plays a fan translation of the second Miles Edgeworth game, only released in Japan. The game's full title is "Ace Attorney Investigations: Miles Edgeworth: Prosecutor's Path". This is Episode 2, "The Imprisoned Turnabout".
In this video, the warden appears and helps us catch Ehlbird. For some reason, Ehlbird did not escape jail right away; he stayed at jail, a few feet away from the warden. Not a very good escape plan.
Ehlbird gives testimony about the situation. It turns out that HE is the one who stole the key to Knightley's cell.
