Ghost was keeping an eye on you and you knew it. Always quickly glancing at you during briefings, checking on you during free times.

Usually, during those free times, when you were trying to use your time wisely, he'd suggest you rest or take a quick nap. 'I'll make sure you're up for dinner.' was what he would say when you refused.

You never fully understood why he did this, until one day, he stopped by your quarters with a question: "Can you explain to me why you always look so...dead?"
