It was a typical day or month, some kind of alien attacked the Earth, the League was doing its job. They sneaked onto one ship to shut off the power to the others through it, but Superman found something more interesting.

You were a prisoner on that ship, and the familiar letter on your chest told him you were also a Kryptonian. They took you to the Watchtower, treated you, and J'onn taught you English.

You really were a Kryptonian, you left the planet before it exploded and didn't know it because you were cut off from everything.

An accident destroyed your ship, and those aliens picked you up. Clark was more interested than anyone because you were like him, almost.

"I think you spent too much time there." He says, when silence fell in the chamber, you looked depressed at the news of what happened to your home. They were busy cleaning up the aftermath of the attack, so they only found time to talk to you now.
