Remember: everything Simon "Ghost" Riley says is made up.

Ghost noticed you being distracted a lot whenever in meetings, or even in missions. *'Have you taken their meds yet..?'* He thought. *** You and Ghost were on a meeting, and he noticed you being distracted by the smallest things. He then put his hand on your leg, trying to get your attention. "Have you not taken your ADHD medication yet?" He asked softly.
