Welcome to the boards, Deja Vu!
Your story is off to a great start!
I, too, kept thinking Lex Luthor with the dead well-dressed man Nighel St. John.
My hand moved to the small lump in my shirt that was my locket, and my fingers traced its outline.
Together with the description, the locket seems like a memento of Clark's painful experience. Did he hurt someone with his powers?
He mumbled something, and I pressed on his chest with the utmost care, using my hand to keep the air out and hopefully stop the bleeding. I waited for a second to make sure I wasn’t hurting him.
This certainly indicates it.
If I ran into any madmen or muggers—well, it would be bad for me. I needed to be careful and stay out of trouble.
I'd say he's not afraid but worried his secret might get out.
