TRUE BROMANCE: Detectives Kevin Ryan and Javier Esposito are more than just partners -- they are the ultimate bros. They've shared the same coffee stirrer, coordinated elaborate fistbumps, and endured a harrowing water torture with courage and humor. And though their bromance has been tested by women, cases, and even keeping "Caskett" a secret, in the end, Ryan and Espo always have each other's backs.
Here are a few of our favorite pics of the 12th Precinct's "brothers from another mother." What's your favorite Castle bromance moment? Share it in the comments below!
