The flashlight in Otacon's hand jerked up instinctively at his approach, but he quickly lowered it again when he made out Fox's dark outline and now familiar voice. His eyes widened a little at the sight of the metal sword, and he briefly flashed back to the actual first time they met, nine years ago, a cyborg ninja and terrified engineer. In different circumstances, Otacon might've smiled at the way things had changed, and the few ways they hadn't.

Right now, however, the memories at the forefront of his mind were of a broken arm and a broken face, and the distant glint of sunlight coming off two primitive but dangerous-looking robotic arms. "Fox," said Otacon, voice full of urgency. "Where's Big Boss? Snake's planning to see him tonight." He looked past him back down the corridor, and angled the flashlight beam towards the doors. "Or... he might've already found him."
