"Castle" fans already can't wait for the premiere of the fifth season of the ABC police procedural. Ever since the last season ended, speculations about the next season surfaced online but amidst all these predictions and the fans' excitement, Stana Katic aired her sadness over Penny Johnson Jerald's exit from the show.

Katic recently exchanged tweets with the fans of "Castle" but was very careful not to spill major details about its upcoming season. Admittedly, Katic said that she does not know that much about season 5 that's why she can't tease anything about it.

Enstarz reported that the actress also offered kind words towards her former co-star Penny Johnson Jerald when she was asked to comment about Jerald's departure from the show. Jerald, who played Captain Victoria Gates in the series, was not tapped to return for another season, which saddened fans and even Katic.

"She's a wonderful actress & gr8 human.Looking forward to our next time 2gether", Stana Katic tweeted with a broken heart emoji.

It took Stana Katic quite some time before she confirmed her return for "Castle" season 5, which sparked speculations that the actress will be leaving the show. That's why fans celebrated when she announced that she is still very much attached to the show.

We previously reported that online predictions about season 5's plot include the possibility of Richard Castle, played by Nathan Fillion, and Kate Beckett becoming parents in the new season.

Carter Matt on the other hand speculates that there might be new faces in "Castle" season 5 while also wishes that Jon Huertas and Seamus Dever will each have an episode that focuses on their characters.

Stan Katic expressed her excitement over the new season but also admits that she was saddened by Penny Johnson Jerald's exit from the show. There are so many exciting things on "Castle" season 5 though, that makes it hard for fans to wait for two more months before the ABC police procedural premieres.
