Marceline's P.O.V.
I looked at my brother. I had spent the last hour trying unsuccessfully to cheer him up.
"Dude, can you quit being such a sad sack?" I said exasperatedly. "I give up, really. I'm trying to help you!"
"Marcy, I don't think you understand. I loved Fionna. I've loved her pretty much since we met. And she goes and does something like that? I give up." He shook his head, sitting against a tree, knees drawn up to his chest. "She's too good for the likes of me..."
"You can't give up!" I cried. "You just can't!" I sat cross legged next to him. "Listen, you remember that brunch picnic party thing Bonnie setup for us the first day you guys were in Ooo?"
He gave a muffled affirmative.
"Well, I was talking to one of my friends, and she was pushing me to make a move on a guy she knows, and she told me something which I've found very true about love." I told him. "'You should always follow your heart, and, if you show them how much they mean to you, they can't ignore it. They'll understand, and, in time, they might even love you back.'"
He sighed. "What guru said that?"
"Cake, Lady, Jake, Incendia (Flame Princess), Simon, bits of it." I paused. "But the whole thing, all put together, was from Fionna."
He sat up, taking a deep breath. "Okay, Marcy. I'll keep trying."
"Just... don't get all in her face about it, 'kay? Just be yourself." I stood and held out a hand to help him up.
He took it and stood. "Thanks... Scales."
"No problem... Casper."
