The System!

Zion interrupted when he thought about how the system was gone. "You weren't even here. How can my progress be recorded?"

"Just the same way as I had recorded how you spent a month here!"

Zion's eyes narrowed. "And how the heck did you record this?"

"Well…." 007 coughed and averted his eyes. "My hardware is already inside your mind, and cannot be removed until we finish the mission, but I'm a software, and I didn't really leave physically. I went into hibernation as my boss hacked into my system. Then he upgraded me from top to bottom, and created new features! Don't worry, host. Many things were on autopilot in the background, so even your progress was recorded."

Zion nodded in understanding and gestured to the system to continue.
