At the Maverick Hunters base, people were in a slight panic because during a mission X was injured badly and had to be powered off for repairs, Zero was pacing back and forth trying to figure what to do when the leader decided to send someone else to fight the Mavericks aka you. Zero on the other hand was a bit confused but he didn't say anything, instead he silently followed you to the different places that you were sent to, He would keep an eye on you from a distance and help if he can.
