Chuck Lorre was asked at the Television Critics Association press tour about Charlie Sheen and the chance of him coming back for the upcoming season finale of Two And A Half Men. Lorre responded with, "I think we're going to have a finale that you're going to be very pleased with. That's all I'm going to say about it."
This would have been a fine answer as it would made reporters move on, which they did… but it must not have sat well with Lorre as he came back and said, "It would be inappropriate to not acknowledge the extraordinary success we had with Charlie, and how grateful I am — we all are – for his contributions. There is nothing but great feelings for the eight-and-a-half years we worked together. But how to wrap the show up? It's tricky…Because, in a way, the show morphed into something else entirely for the last four years, and its something we love. And we want to honor both. How to honor both is the challenge of this finale.The other challenge is how to get people to watch something without telling them what it is." And he ended it with a smile.
It seems he is either hinting the Sheen will return or he's trying to throw enough doubt out there that folks will want to tune in to find out.
