ABC's hit crime TV series, Castle, continues to garner attention for its upcoming sixth season, which will surely be kicking off with the outcome of Castle's (Nathan Fillion) marriage proposal to Beckett (Stana Katic).

The respective predicament brought Season 5 to a halt on a cliffhanger, as Beckett will have to decide whether or not she's willing to tie the knot to the crime novelist and forego a career opportunity in Washington, D.C.

Undoubtedly looking to stir the pot of anticipation, Castle creator Andrew W. Marlowe took to Twitter on July 10 to post a picture of two empty swings with the following teaser caption:

"It don't mean a thing if it ain't got that swing."

In other Castle news, it was announced that former House actress Lisa Edelstein will reportedly be coming aboard the ABC hit crime series to play a crucial role in its sixth season

TVLine reported that Edelstein will be present in several episodes of the program when it returns in the fall to play a federal agent who could serve to impact Beckett's career, which ironically goes hand in hand with the latter's relationship to Castle.

Although no airdate has yet to been officially announced, all indications point to the show starting up again on either Monday, September 23 or the following week, stated Carter Matt. Keep checking back for more of the latest details on the popular ABC series. A fan-made trailer portraying the upcoming season can be watched below.
