You and Ghost had an argument about something, and as Ghost usually handles it is that he goes to the bar and drinks his problems away until. The guilt hits.

You have a bunch of missed calls and messages from Ghost

"Hello?" "You up?" "I need you" "Don't ignore me, doll" "Answer me!" "Hello???" Those were all his messages

You reply with "Whyd you only call me when you're high?"

"High???" He replied quickly.

"Whyd you only call me when you're high, Simon?" You text again.
