'Castle' Season 6 SPOILERS: Two New Trailers Released for Episode 1 "Valkyrie" / Premiere Date September 23 on ABC [TRAILER]

Castle Season 6 SPOILERS!

Guess what Castle fans? Two new trailer previews have been released for the Season 6 premiere.

In the first trailer, Beckett reacts to Castle's proposal to marry her. She doesn't say yes, but she doesn't say no. She confesses her love for Castle but the trailer ends before we get an answer. We're left with something serious Beckett needs to tell Castle before she can let him marry her.

In the second trailer, Castle sees his mom and his daughter Alexis is back from her trip to Costa Rica a little early. At first Castle is excited to see his daughter until he finds out she brought back a special souvenir; a new boyfriend.

Alexis introduces her new boyfriend Pi to her dad. After an awkward exchange [I've never heard Castle called Mr. C] the worrisome father can't believe the new boyfriend is staying in his house.

Castle Season 6 Episode 1 "Valkyrie" is set to premiere September 23 on ABC.

Here's the first trailer for the new season:
