It wasn't a choice that Fox wanted to make. Choosing between Big Boss and Snake... even when it had seemed like he'd chosen Big Boss, Fox knew that he wouldn't ever be able to completely give up on Snake.

It was almost a relief to have the topic changed, which it apparently was when Big Boss looked curiously at something behind him. Fox picked up on it quickly. He needed to show Big Boss what had happened, to explain it. "I told you this place was an experimental facility," he said. Fox carefully sat the sword down on top of the dresser, pulling his hand away from Big Boss so he could remove the jacket and both shirts he wore beneath it.

"They decided I'd make a good test subject. It's attached to my spine," he said as he turned around, exposing the long scar that ran the length of his spine and the blue, strange tendrils that spread out beneath his skin from the implant on his spine. "They... also don't believe in anesthetic," Fox added, his voice much softer as he said that, "Or painkillers." It wasn't necessary to add that piece of information, but Fox did anyway. Big Boss needed to realize how monstrous this place was, and realize he didn't need to add to the pain.
