To understand this story, read SageK's story 'A tavern is a place where madness is sold' first. They were kind enough to let me use Fi and Liam. Thanks!

Most of this idea goes to SageK.

Disclaimer: do I really need to say it? Fine. *sighs* NO, I DON'T own Castle. Too bad.

Javier, Kate, and Castle had seen Ryan's Irish Pub full (St. Patrick's Day), but not this full. Christmas lights, merry songs that were somewhat in the theme of Christmas, and lots and lots of people.

The first Ryan family member they spotted was Fi, green leaves woven into her braid, wearing a red rose flower crown that was- had to be- bobby pinned to her head. Kate waved her over after Fi had finished reprimanding Liam and his group of friends for darts.

"Hello!" she greeted cheerfully. "Kevin's over there. Súile gorm!"

Kevin had been teaching Javier some Irish, so he was slightly able to understand. "Blue eyes?" He questioned.

Fi laughed. "Yes, us kids have nicknames for each other in Irish. Keeps the family together." Kevin could be seen weaving through the crowd. Wading, more like. He flashed them a smile and sat down next to Javier.

"Hey, guys. Hey, bláth." Flower, Javier realized. Fit pretty well. When did Fi not have flowers in her hair?

"WE WISH YOU A MERRY CHRISTMAS, WE WISH YOU A MERRY-" Fi frowned, taking off after the voice. Which quickly raised two octaves. "HOly sHIT!" The group laughed. Fi may be small, but she's terrifying.

"So, how do you guys like the pub?" They nod their approval, and Kevin beams. "Great, because I have to work here alot, and you might get in free." Castle's grin widens, and Kate smacks him on the arm.

BLAM!

Heads turn, and there's Liam, holding the biggest handheld cannon. Leafy red berries rain down, and everyone realizes it's mistletoe. BLAM! Another shot goes off, and people are laughing now, kissing whoever they turn to.

"LIAM!" Bellows Mrs. Ryan, and said person gets that 'oh shit' expression. He takes off and dives underneath the group's table, behind Kevin's legs. "LIAM RYAN! WHERE ARE YOU!?"

People are watching the spectacle, amused.

"Súile gorm, ach amháin dom!" Squeals Liam, getting an annoyed look in response.

Kevin replies in English, "What do I get in return?"

"Anything?"

"Anything?" Kevin dares, and the younger Irishman realizes his mistake. Mrs. Ryan is still yelling for him, marching around the whole pub. "Like, you'd do my chores and clean my room, and-"

"YES!" Liam practically screeches when their mother spots him. Kevin shoves him out from underneath and guides him around people, hand firmly on his younger brother's wrist.

Castle's jotting things down, and Javier grabs the notebook. "C'mon, bro! Why are you taking notes like this is history class or something? Relax!" Kate nods in agreement and Castle's face falls.

"But- but-"

"No buts!" Kate snaps right as Kevin reappears with his mother hot on his heels.

"Mammy, I don't know where he disappeared! Honest!" His baby blue eyes goes into bamby mode, and no mother can resist that.

Mrs. Ryan sighs. "Alright, Súile gorm, but if you're lying..." and off she goes, sliding back towards the counter where Fi's warding off college frat boys. Kevin turns to the group with a sly grin.

"So," he says, waving Fi over. "Howzabout we go to the Ryan household and watch some movies?"
