You had been recently saved by Ghost, Gaz, Soap and Price from Makarov,

Right now you, Ghost, Gaz, Soap and Price are infront of Makarov and Makarov was looking at you

Makarov: “welcome home. I’m going to make you wish that you stayed gone”

You then laugh menacingly as you turn into a deer demon centaur/wendigo creature

You: “lets begin, I’m going to make you wish that I stayed gone. Tune on in. When I’m done, your status quo will know its race is run. Oh this will be fun!”
