The September 19 episode of 'Two and a Half Men' indeed features Charlie Sheen's character being hit by a train, and Kutcher's character entering the house after a failed suicide attempt.
It turns out most rumors surrounding the demise of Charlie Sheen's character on "Two and a Half Men" are true. In the premiere episode of season 9, Charlie Harper indeed died because he slipped on a subway platform in Paris and was hit by an oncoming train. His neighbor Rose described the accident, "His body just exploded like a balloon full of meat."
At Charlie's funeral, his brother Alan spoke in front of a coffin and one of Charlie's signature shirts. He claimed it was a sad day for everyone and stated that his brother gave everything he got in life. Charlie's exes later retorted about sexual diseases that they had contracted from him.
Alan received Charlie's house in his will, but he could not afford the mortgage payments so he held an open house to find a buyer. John Stamos, who revealed he had a fling with Charlie, came to the open house, and so did Thomas Gibson and Jenna Elfman of "Dharma & Greg". Neither of them, however, bought the house.
Alan also considered to dispose Charlie's ashes on the nearby beach, but they were spilled all over the floor when Ashton Kutcher's Walden Schmidt surprised him by appearing at the doorway. The internet billionaire was all wet after failing to commit suicide in the ocean.
Walden and Alan went out for a drink, and the former brought two women to Charlie's home. Walden appeared naked toward the end of the episode, telling Alan, "I dig your house. I'm going to buy it," because his wife would not take him back.
