"I'm sorry," Finn whispers, head bowed so low his hair falls over his eyes like the shadow of shame, wetness dripping down from his eyes like floodgates about to burst (and he cannot simply articulate his regret for how terrible and unheroic he had been towards the Candy Princess of late, he doesn't have the words so all he can do is cry) and Princess Bubblegum crouches down low that she is on eye-level with her hero and kisses him gently upon the bandaged wound she accidentally inflicted.
She whispers to Finn, "I am too," and places her forehead over so gently against his nose. Her hair runs like a standing wave against his golden hair, freed without a hat in the extremity of his remorse, and her hair seems to consume him, an all-encompassing hug.
After a moment, she kisses him again, soft and sweet and more tenderly that words could give in so limited a time.
They can't take back what has been done (and now there is an awareness of wrong being done on both sides, now that there is time to sit and wait, and think), but there can be no blame to be laid, nor bitterness to be nursed.
Finn hugs her, desperately and ferociously, and he sobs like a broken toy in sore need of its owner again. He's openly crying soon, and Bubblegum tenderly takes hold of him and hugs him tight.
She cries too.
They both have reason to cry.
But they are holding each other, and they know of the rifts that must be mended, and jagged and fierce those these rifts are, it is nothing compared to the love they share and the friendship that binds them into something whole.
