After Walden (Ashton Kutcher) donates the late Charlie's piano to under-privileged kids in next week's episode, Alan will begin to unravel. Alan, struggling to come to terms with his brother's death, will end up believing he is Charlie Harper and ultimately check himself into a Malibu mental institution where he'll share a room with Busey in the Nov. 14 installment.

Busey in March addressed former Men star Sheen's "tailspin," offering his longtime friend advice for him to "look at himself and the truth in his heart, because what he's doing is not true to his heart."

The guest turn for Busey comes a few years after the veteran actor -- and former addict who is 13 years sober -- appeared on VH1's Celebrity Rehab With Dr. Drew as part mentor and, ultimately, part patient.
