On Castle, cases frequently get out of hand, but in Monday’s episode, all hell will break loose.

In Season 5, Episode 10, “Significant Others,” Rick has a lot on his plate: Alexis is home with mono; Kate is staying with him while her apartment is fumigated; and oh yeah — his feisty ex, Meredith, temporarily moves in to take care of their daughter.  

However, in a new sneak peek clip, Castle and Beckett aren’t fighting with each other — they’re watching in horror as a suspect (General Hospital alum Nancy Lee Grahn) commits a murder right in front of them!

Check out the clip over at TVLine, and then share your reaction below!

Original Air Date: Castle Season 5, Episode 10: “Significant Others” airs on Monday, Jan. 7, 2013 at 10 p.m. ET on ABC.
