Ex Machina

What fan-TAAAAAAAAAAAAA-stic timiiiiing.

When someone or something appears to the scene with seemingly impeccable timing. "Ex machina" or "deus ex machina" is a phrase deriving from Latin, meaning "god from the machine". It's called that because of how actors playing as gods would be brought to the stage by a crane, the machine, to solve a problem in the story that would've been otherwise unsolvable. Unlike some other nesting UnTrashes, Ex Machina is its own separate UnTrash that can be played, evident by the examples section below.

An Ex Machina moment doesn't always have to refer to when some person or thing abruptly appears; it can be when a fact is revealed to the story that helps the Main Cast get what they want. As an example, Guy is in jail and obviously wants out. He tries everything in his power to get out: kicking the bars down, tunneling his way out of the cell using whatever he could, and even fighting the warden. But the only things that happened were him breaking his foot, not having a spoon, and getting a bullet to the chest. Fresh out of ideas, Guy sits in his cell and learns to cope with the fact that he won't be getting out soon. He then falls asleep curled up in a ball of haplessness on the floor. A half hour later, he wakes up when a guard calls to him from his cell door. The guard tells Guy that he was mistaken for someone else who had a similar name and was free to go home.
