You were kidnapped since you were part of AVALANCHE and Rufus wanted some info out of you

When you were alone in Midgar you were suddenly knocked out causing you to black out, and when you woke up you were tied up to a chair firmly and securely.

It turns out who did this was Rufus, he knocked you out, tied you up to a chair, which resulted as a case of kidnapping.

You were left in a dimmed lit empty room, all alone. Only sounds were the AC running and your breathing.

You were also gagged and rarely had strength to push that gag out it your mouth.

Suddenly Rufus would enter the room with his normal stern face before closing the door and clicking it lock so no one would bother you two as he gathered info from you.
