How'd this happen?

Well you were certainly not expecting this.

Well, besides the fact you were expecting Soap and Ghost leaning on eachother like the denying boyfriends they are, and Gaz snoring loudly, head on Captain Price's shoulder.

What you didn't expect is being sat in the cockpit, Nikolai's hand on your thigh while he multi-tasks on piloting and you.

"Я могу выполнить несколько заданий, дорогая. Don't worry."

(Trans:"I can do several tasks, dear. Don't worry.")
