Smallville, Season 4

Clark [in Lionel]:
I know this is hard to believe, but I swear, it's the truth. [Pause.] It's me, Mom. It's Clark.

Martha:
You're sick, Lionel. You need help.

Clark [in Lionel]:
Mom, you have to believe me.

Martha:
I'm leaving!

Clark [in Lionel]:
Mom, Mom, no! Mom, remember when I was six and I was playing tag with Dad, and all of a sudden I started running faster than I'd ever run before, and I was in the middle of Palmer woods completely lost. And you and Dad had to call Sheriff Ethan, and when you saw me, you started crying. And I thought something was wrong with me, and you said no, there wasn't. And then you held me in your arms and you told me I was just special. I'm your special boy, you said.
