Smallville, Season 10

Future Clark Kent:
(to Clark, describing his Lois) She's a handful, isn't she? You're right on time.

Clark Kent:
You knew I'd be here.

Future Clark Kent:
Time travel. Think it through.

Clark Kent:
Because you were me when you went through this and I'm...

Future Clark Kent:
Well done, my man.

Clark Kent:
How did I become so uptight? (looks his future self up and down) And nerdy?

Future Clark Kent:
(irritated) There's no time to chat about how, when, and why! We've been through weirder things and I need you on the roof!

Clark Kent:
When did I start taking orders?

Future Clark Kent:
There's a nuclear reactor that's about to blow on the other side of town. Now, I can't be in two places at once.

Clark Kent:
If you knew it was going to happen, then why didn't you stop it?

Future Clark Kent:
Because then you wouldn't have experienced all this. And you would never have become me.

Clark Kent:
(under his breath) That's too bad.

Future Clark Kent:
Roof. Now. (superspeeds away)

Clark Kent:
(inspired) That's what I become.
