It takes almost four hours by train to travel from Zurich, Switzerland to Bavaria, Germany. Cristina peeks at her clock too often as the only thing she wants now is to get off the train regardless how comfy her business class seat is. As cold and heartless as she usually seemed, Cristina happens to become the bridesmaids more often than she would love to in her friends' weddings: Izzie's, and April's, and so on.

It is five p.m when the train finally arrives at the station. Putting the documents she's working safely inside her briefcase, Cristina collects her luggage and gets off the train.

-Cristina!

The calm and sweet voice of Teddy Altman among the crowd makes Cristina smile. "Hey!" She waves at Teddy, but her happy face falters as she sees Callie and Arizona standing just right behind Teddy.

"Cristina!" Callie shouts enthusiastically.

Cristina can't help but fake a grin and wave at them as she hauls her luggages towards the group waiting for her. "Hey. Glad to see you all again. It's been…years!"

"I know right? Look at you! I can tell Zurich has treated you so well," Callie laughs while giving Cristina a big hug.

"Thanks for coming, Cristina. It means a lot to me."Teddy smiles and pats Cristina's back and offers to help her with some of her luggage. "Let's go back to our place!"

Cristina intentionally slows down her pace and let Callie and Arizona walk pass them them. Realizing Tthe change in her student's facial expression as soon as she saw Callie and Arizona, Teddy walks slowly to Cristina's side, "Hey, what's wrong?"

"You never said you were inviting Callie and Arizona. You said it's gonna be a small wedding." Cristina mumbled in her clenched teeth.

"I know. But, most of my friends are dudes in the army, so I only have you and my cousin as my bridesmaids. At the last minute, my cousin said she could not make it due to her job interviews of some kind, so Arizona is the closest girlfriend to me other than you."

"And..?"

"And Callie is Arizona's wife." Teddy beams at her.

"I get it. It's fine. It's just that I haven't met them in five years. You put me into big troubles now."

"You'll be fine. Just enjoy your little time here as if it were a…little vacation. I told them the same thing, too. Am I lucky to be able to invite all the best surgeons from over the world to my wedding?

"All the best surgeons? You mean…" Cristina trails off, her face changing from surprise to panic. Before she can ask all of her questions however, Callie calls them from ahead:"Common, guys! Speed up please!"

Cristina can see the happiness in Callie and Arizona's eyes. They all indeed enjoy their little vacation of Teddy's wedding. She is a little bit nervous thinking about meeting her old friends from the US again. Taking a deep breath, she talks to herself, "Well, I should enjoy my little vacation, after all. I've just got funded another ten millions for my hospital in Zurich."
