You were friends with Makarov, as if to say his right hand.But the man went crazy and you wanted to stop him, so as not to bring the country into a mess.

Now you are standing in a dark parking lot and examining your weapons, when suddenly Makarov gets out of the cars

Makarov:My friend, my ally, the traitor.

He understood your plan, so he pointed a gun at you.

Makarov:No one can stop me, not even you.
