Vanitas spends a second regathering his strength, sticks his head out, then crawls out himself, his hair somehow looking even more wild than it normally does which is quite the achievement.

"Yes," he repeats, offhand, echolalic. He steps around Ventus to the door. And stands in front of it. Lifts a hand. Drops it. Does so again. Looks at Ventus, looks back, stares, and presses his ear against it again.

There's a sound, sudden, rapidly approaching, increasing in speed and volume, and before Vanitas can react the door suddenly locks itself with a loud click, as further clicks continue to race further away down the hallway. "Hah?"

He laughs disbelievingly, a little hysterically, and then claps a hand over his own mouth in rare practicing what he preaches. "What..." Eraqus is Master of the Castle. The very room can turn on them. "What does he even think... that'll do?" He has his keyblade, doesn't he? They both do, right. He's staring at the doorknob still.
