Gotham, Season 4

The Riddler:
[whistles] You don't look good. Think you might be exceeding your recommended dosage. You experiencing... "Trembling Extremities?" Check. "Cognitive Imparement?" Definite check. Though, to be fair, how would you know? [laughs]

Edward Nygma:
SHUT UP!!

The Riddler:
Take all the pills you want, Ed. I'm only getting stronger. Soon, I'm gonna be out... and the FUN begins!

Edward Nygma:
No! I won't let you. 'Cause I know what you'll do.

The Riddler:
Oh, you mean, kill Lee? Yeah, I guess I will do that. And you can't stop me-

Edward Nygma:
There are things that I can do!

The Riddler:
Like what? You need to face it, pal. The only way to get rid of me, is to kill yourself.

Edward Nygma:
...I guess you are smarter than me.

The Riddler:
...You wouldn't-

Edward Nygma:
I would. Oh, yeah.
