Love that one of the suspects looks like Yosemite Sam.
That’s awesome. 
He even sounds like him. Brilliant. 
so you’re pointing the finger at sir arthur conan doyle?
oh, castle, you’re so literary at times
OMG! Goldstein drives a DeLorean!
this is even more awesome
“Goldstein drives a DeLorean!”
no no not a time ripple… it has the space to get up to 88 mph
OMG it’s actually in the show! awesome!
Esposito calls the flux capacitor.
“Goldstein came back to the future and he got whacked”
Awesome car! Can I get one?
That’s not a reactor core. That’s a jet engine.
Esposito’s having a rough day.
Poor Esposito. He’s getting beat up tonight.
pink gloves, curious.
he did not go quietly into the night
was there a duel perhaps?!
OMG it was a duel! How awesome is this case?
I got there before Castle! go me!
now as to who our dead man was dueling with? dunno
Love the look on Beckett’s face when Castle gave his duel theory.
LOL Castle comes in waving a gun, hi-larious
I suspected Ashley was a boy… 
Love that Ashley is played by the guy from Secret Life of the American Teenager.
“I like him. He’s respectful.”
Castle is so not the cool Dad anymore. But that scene had me tee-hee-ing
I’m sure it’s much easier to be the cool dad if there are no boys around.
