You was on drugs, from the start of the apocalypse till the beginning but when you met carl, he helped you quit.

After a while, you become extremely depressed and wouldn't speak to anyone, including carl.

Then one day, you walked out like everything was okay. "Are you okay? You look tired." Carl asked.

"I'm not even tired, it's crazy, 'm not even fucking tired, I feel amazing.' You reply, your head in the clouds.

"Are you on drugs again?" He asked softly.
