Adventure Time, Season 4

Bubblegum:
Finn!

Finn:
[high-pitched] AAHHH!!!

Bubblegum:
Whatcha doin'?

Finn:
Oh, uh— hi, Princess! I'm, uh, writing something for Jake.

Bubblegum:
Oh, well, speaking of Jake, did he explain everything to you?

Finn:
Yeah.

Bubblegum:
And you understand?

Finn:
[turns away] Yeah, I understand.

Bubblegum:
Finn, sometimes you want someone and you [puts hand on Finn's left knee] want to kiss them, and be with them. But you can't, because responsibility demands sacrifice.

Finn:
[incredulous] What are you trying to say?!

Bubblegum:
I'm trying to say that you're a hero, Finn. You're my hero. So, I'm glad you understand why you can't be with Flame Princess. [Finn stands up, enraged]

Finn:
Bubblegum, I can't do this anymore!!

Bubblegum:
What?

Finn:
Now you like me?!

Bubblegum:
Finn, what are you talking about?

Finn:
What am I talking about?! [grunts] PB, I was... geh...eh... I was in love with you! Okay?! And you didn't love me back! Now I'm ready to move on, and it's like... [grunts] you're gonna build me up all over again! Well, I'm done! I'm done.
