According to my friend, it happened, the world ended. Now you may be wondering how I could even have this chat with him if the world ended. Not to worry, there is a perfectly reasonable explanation...
I am not me, and he went into a different universe when the previous world had collapsed. Apparently I wasn't so lucky, nor any of the other 8.1 Billion souls. Only he got to come here, because his original self was already dead. How I wouldn't have remembered him dying and doing a Jesus, is beyond me...
This all leads me to the conclusion that my friend stopped taking his meds and has been binging rick and morty again.
