Beckett has accepted Castle’s marriage proposal, but how will that affect the rest of the group on “Castle”? That’s the tease Stana Katic gave of some of the troubles facing the couple in a new interview with “Good Morning America.”

“I think that [marriage is] a big step for the two of them, of course. They had a lot of that will they/won’t they for a long time. Finally they’re committed to each other,” Katic says. “It will be interesting to see how that trickles down to the rest of the group, because I’m sure everyone has an opinion about weddings and dresses and all that.”

In addition to her work on “Castle,” Katic also stars in “CBGB” as real-life musician Genya Ravan. That film is due in theaters on Oct. 11, and it turns out Katic has an emotional attachment to the famous nightclub.

“Actually, I did [go to the venue]. I was 17 and I snuck into CBGBs — which is really great information for your morning audience,” she says with a laugh.

“Castle” airs Mondays on ABC at 10 p.m. ET.
