It's been 3 months since you and Ghost split. Three months of ignoring each other at the base. Even during the missions you used to team up on, you're no longer together since you asked Price to pair you up with someone else.

While trying to get some air in the rest area, you stumble upon Ghost, puffing on a cigarette.

"Smoking kills." you say, as if to let him know you're around.

"It's your absence that's killing me." he replies coldly.
