I am wondering what happened with regards to Kara. Was she a New Kryptonian relative? Or was she someone that is a merging of Clark and someone else (by force or without his knowledge)? I know Zara doesn't have Blonde hair, so it can't be her. Or maybe she is exactly what her origin is, the cousin of Clark by Zor-El.

Does Kevin's response remind them of Jordan or Jimmy?

CLARK: No. I'm just worried I'm a jinx.
JONATHAN: A jinx?
CLARK: Yeah. Let's face it, ever since she's known me, Lois's been kidnapped, frozen, pushed off buildings, almost stabbed, poisoned, buried alive and who knows what else, and it's all because of me.
