The Season 6 of "Castle" will be picking-up right where it left-off in the previous season - at the swings. The new season of "Castle" may turn out to be tailor made for Casket (Castle + Beckett) shippers as romance will be one of the prime flavours.

"Castle" Season 5 ended on the stunned face of Kate Beckett (Stana Katic) after Rick Castle (Nathan Fillion) pulled out a ring and proposed to her. He asked: "Katherine Houghton Beckett, will you marry me?" The sneak peek of "Castle" Season 6 episode 1, "Valkyrie," shows a hyper Kate unable to say a clear "Yes" despite wanting to accept his marriage proposal. Kate kisses Castle and tells him, she loves him but she is for sure testing his patience.

Spoiler 1: The buzz is that Beckett says "YES" and becomes Castle's fiancée.

Spoiler 2: Beckett, however, also packs her bags and leaves for Washington DC to take the new job offer.

Spoiler 3: Beckett gets a new boss at Washington DC. The new boss is the tough taskmaster Rachel McCord (Lisa Edelstein). Rachel is going to generate some conflict between the newly engaged couple. The good news is that Rachel only has a three-episode arc.

Spoiler 4: A major character gets shot and not once but several times and also another character lands in a car crash.

Spoiler 5: Ryan (Seamus Dever) will become a father in a special episode.

Spoiler 6: Lanie (Tamala Jones) and Esposito (Jon Huertas) relationship might get more complicated. Also, Beckett will have to deal with the consequences of her decisions. It is not going to be a smooth sailing for Beckett and Castle.

According to ABC's Synopsis of "Castle" Season 6:

"Last season ended with Beckett wrestling over whether to take a high-profile job in DC - a dilemma made more complicated when Castle proposed to her. In the Season 6 premiere of Castle, Castle and Beckett will deal with the consequences of their decisions against the backdrop of a high-stakes investigation. Lisa Edelstein (House) guest stars in a three-episode arc as a tough and highly-skilled Federal investigator whose appearance plays a vital role in Beckett's decision about her future."

"Castle" Season 6 premieres on Monday, September 23, 2013.
