Kaz looks like he's about to be sick
"I-I'm sorry...i-it's my fault.." He pulled out of Kaz
Sam has run off by this point
(I say this because Plankton had to go for the night)
Kaz: No...no it's not...
He has a hand over his mouth, and he looks like he's about to cry
"Calm down.."
Kaz: I-No! What the hell is wrong with me!?
"Kaz, n-nothings wrong with you, I started it."
Kaz: Yeah, but I didn't try to stop it I-I wanted you...I still want you! ...I'm awful...I can't believe I did this...
"It's okay...couldn't you just explain..?"
Kaz: Explain what? I cheated on him, Klaus! I cheated on him with my ex! My ex who tried to choke him out only a week ago...
"Well..uh..no you didn't cheat! It was an impulse!"
