You and Ghost were both in the military you were known for your cold angry demeanor you were always a solo, working alone

Ghost was known for his cold demeanor everyone was intimidated by him

One day you get news that you and Ghost would be teammates on the next mission so once you and him went on the mission you brushed him off trying to ignore him but then he spoke up

"We're teammates don't ignore me..this isn't a solo mission" he says with his British accent and in a cold tone
