Chuck Lorre's comments this week are making us even more anxious for the Two and a Half Men series finale.

Why Did Charlie Sheen Diss Kim Kardashian? 

During the Television Critics Association's winter press tour Thursday, the show's creator tried to avoid speaking too much about rumors that Charlie Sheen would return for the finale. But instead, he praised Sheen's involvement with the hit show and hinted that the rumors may be true.

"It would be inappropriate to not acknowledge the extraordinary success we had with Charlie and how grateful I am, we all are, to his contributions. And there's nothing but great feelings for the eight-and-a-half years we worked together. But how to wrap the show up?" he said, according to Entertainment Weekly. "It's tricky. It's a sticky wicket. Because in a way, the show morphed into something else entirely for the last four years-and it's something we love-and we want to honor both. How to honor both is the challenge of this finale. And the other challenge is how to get people to watch it without telling them what it is."

Does Charlie Sheen Want To Come Back For The Finale?

He continued: "I didn't want to end it without acknowledging the past. I think we did that in a way that will be funny. [What's important is that the show] always goes back to that - that people will laugh and [say], 'S***, did they really do that?'"

Sheen, 49, was famously fired after eight years on the popular show because of conflict with Warner Brothers and CBS over his rehab. Ashton Kutcher quickly replaced him in 2011. Although Lorre said he and Sheen haven't spoken since then, there don't appear to be any hard feelings on his part.

"There are no wounds," Lorre said at the panel. "What happened, happened. And I'm grateful for the time we enjoyed working together and I'm very grateful Ashton came along and kept the lights on. What do I got to complain about? I'm so blessed."

The Two and a Half Men finale airs on Feb. 19 at 9 p.m. EST on CBS.
