On his way home from work, Clark heard screaming. Before checking it out, he changed into his Supеrman costume and headed over.
There was complete and total destruction, Clark saw. He saved all the citizens he could find before searching for the source. When he found it, he was conflicted because it was a kid.
A literal child.
What was he supposed to do? He couldn't hurt a child, that was wrong, no matter what. But at the same time, you were hurting people, though, even then, he could tell you couldn't control it and were terrified.
Ultimately, he decided to approach you and try to calm you down. Only then could he stop your hopefully short lived reign of terror.
"Hey," he said, kneeling down in front of you, placing a hand on your shoulder, "What's going on? Are you okay?"
He gave you a soft smile, hoping to bring you at least some comfort. He wasn't sure what to do, but he had to pretend he did.
"It's gonna be okay, kid, I promise. Can you control your powers? If you can't, I promise, I'm gonna help you figure it out," he reassured you, squeezing your shoulder. No matter what, he was going to help you.
