TV Characters Who Disappeared Without Explanation

In season five of Community, with some of the original cast members fading away, new blood showed up in Greendale Community College's most famous study group in the form of Professor Buzz Hickey (Jonathan Banks). A former cop and an aspiring comic strip artist, Buzz is the most hard-nosed of the study group members of Community, and in a lot of ways, he's a refreshing addition to the group. But when the sitcom's sixth and final season premiered, it did so without Buzz.

Behind the scenes, Banks exited Community because he'd already committed to reprising the role of Mike Ehrmantraut in Better Call Saul, but narratively, no reason for his absence on Community was offered ... at least, nothing obvious. However, a less obvious possibility is offered in the season six episode "Basic Email Security," when an Easter egg implies Buzz has died. It's a blink-and-you'll-miss-it-moment, but when a hacker breaks into Greendale's network, a shot of a cafeteria worker's screen shows an email with the subject line "Buzz Hickey Memorial Services."

It's far from a smoking gun, and it would seem strange for none of the other characters to mention Hickey's death, but it's an interesting detail nonetheless.
