The awkwardness was not something that Fionna could be fine with. She saw way beyond the sniping and boyfriends and stuff to see that Marcie and PB were actually really close and liking each other in that way. She knew it, but they were sorta trying to tiptoe around it, which was just weird to her. What was the point of liking someone if pretending you didn't got you all upset and sad and junk?

She chuckled, and walked over and gave Marceline a playful shove. "You guys are dumb. You argue all the time or whatever. What for? You're both really cool and should just have fun and do stuff."

And at the chest part, she laughed. "Man, I don't even care about that junk. I have a lot of chest too, more than both of yalls, and you don't hear me complaining!"
