Since Nikolai 'rescued' Fyodor and Dazai from their cells, the jester has been nothing but joyous and excited,

Fyodor looked through a piece of glass from a mirror, he saw Nikolai frown through it, but when the russian moved it away, Nikolai was his usual happy self. Dostoyevsky looked at his jester friend, "Oh Dos-kun!!~ How i missed you bestie!!!" Nikolai said joyously, though Fyodor knew he felt the opposite.

"Don't try to fool me, Koyla. I know you're sad." The russian stated plainly, having a slight tone of worry in his tone.
