The Castle family will be expanding in Season 6, and although it’s Kevin Ryan’s (Seamus Dever) baby that’s joining the bunch and not a Caskett offspring, we’re still psyched for the little one’s arrival.

But will creator Andrew Marlowe give viewers a peek at Ryan’s firstborn, or will we just hear about the kiddo?

Andrew told Entertainment Weekly that they have just started to discuss Baby Ryan’s arrival, but it’s likely that viewers will get a glimpse of the newborn. “My assumption is we will get to meet the baby and that the episode will be late this fall.”

And what else can we expect from Season 6?

After a few serious episodes, like the decision-ladden season premiere, we’ll get a couple of light-hearted instalments such as the Saved by the Bell parody episode. Andrew also said that viewers are in for some adventure, noting that one episode scheduled to air during the first half of the season will have a “Da Vinci Code/National Treasure” feel to it.

The sixth season of Castle kicks off on Monday, Sept. 23 at 10 p.m. ET on ABC. Are you ready for it?
