Karael goes on a vacation to Texas only to come back with Ebola. He is admitted to a hospital while the Grim Reefer goes back to Hell to convince his brother (The Grim Reaper) not to kill Karael.
Not much is known about what happens at the end of this episode. Karael (The User) listed this as "The last episode featuring the character". This could mean he would die, or move away.
