Esposito is about to take drastic measures to get Fosse to talk when he finds the bomber bleeding out in his cell. The suspect stabbed himself in the neck with a pen. Turns out Fosse had brain cancer. He was dying and figured to take a few of his enemies with him. That now includes Beckett, who is starting to feel fatigue. Castle embarks on another effort to take her mind off the situation. More memories are recalled about all the times others told Beckett that she was crazy about her partner. As for Castle, he’s lost in thought about all the revealing outfits Beckett has worn over the years just to get his attention. She claims it was all in the line of duty.
Castle refuses to admit that he was hanging out with Beckett all those years because he was into her. He just loved playing cop. The debate about who liked who first rages on. Esposito and Ryan believe the bomb buddies are starting to crack under the pressure. Things go from bad to worse when the bomb squad learns there’s a timer on the device. There’s less than 30 minutes before it blows. Castle promises they’ll get through this. They’ve been in scary spots like this before. Of course, the most terrifying moment was when they were nearly caught in bed by Martha after their first night together. Talk about close calls.
Castle believes the suspect’s story will lead them to a solution. It’s worked for them before. They realize that Fosse may have been luring the baseball card collector to his apartment for a reason. This info may be too little too late. There are only 10 minutes before the bomb blows. Beckett made Castle promise to leave her alone when the time came. The two of them exchange a heartfelt “I love you” before saying goodbye. Beckett leaves a voicemail message for her dad to say she loves him, too. She recalls so many emotional memories as she stands alone with closed eyes. Then she’s not alone anymore. Castle is back. He brought coffee.
