Marco didn't know what was happening. He looked around, wondering where the hell he was. He must have blacked out, because Jean stood a little ways away from him, shoulders hunched.
"Jean?" he asked, but to no avail. Sighing, he tried again: "Jean?" He was slightly upset that the other man ignored him. Then he noticed that Jean's shoulders at began to shake. "...Jean?" he asked uncertainly, voice small as he'd never seen Jean breakdown before. The other man sobbed, sinking to his knees and exposing the reason for his tears.
Marco stared in horror at his own half-eaten body. "Oh my god," he choked out, and he walked shakily towards Jean. Said man was clutching his corpse, crying atop of it without restraint. Marco's lip quivered. "Jean, I'm sorry," he whispered, laying a hand on the light-haired man's shoulder.
Jean stiffened as if he felt it, and turned to look towards Marco. "...Who's there?" he asked, voice cracking. "Marco..?" he croaked, eyes swollen and red.
"Jean..."
The man didn't seem to hear him, so he wrapped his arms around the other and felt him begin to shake once more.
"Jean, I'm sorry. Jean... I never meant to leave you alone..."
Jean broke down once more, and it took the aid of Sasha and Connie both to pull him away from the body. Marco watched with sad eyes as Jean left, his own soul fading the further Jean walked away.
"Goodbye, Jean."
