Hello!

I'm going to post a new chapter of this story every Sunday and I have 10 chapters planned. There may be more, but we'll see.

I know that the Grey's Anatomy timeline is years after the Harry Potter books. But let's just say that the war is going on at the same time as Arizona's time at Seattle Grace Hospital. And Arizona and Tonks would probably not be the same age, but let's pretend.

I also want to add that just so you know; this story is going to jump a little in time. Not every detail from the books or the tv-show is in here.

Canon pairings: Arizona/Callie, Tonks/Remus, Bill/Fleur

Chapter 1 – Doctors

"Wotcher, do you know where I can find dr Arizona Robbins?"

"Oh, she's right over there", the nurse replied and pointed to a woman down the hall.

"Oh, right… thanks", the pink-haired woman said.

She walked towards the blonde and shouted with a grin; "Dr Robbins!"

Arizona turned around.

"Oh my god, Tonks!" she sighed but smiled at the same time.

The woman – Tonks – reached her and pulled her into a hug.

"What are you doing here?" Arizona asked when she let her go.

"Oh, I can't visit my weird friend who chose the muggle community over the magic?"

"Sch!" Arizona hushed, looking around to see if anyone heard.

"I still can't believe you became a doctor!" Tonks exclaimed.

"A surgeon", Arizona added.

"Yeah, yeah, whatever. Same difference."

"And come on", Arizona continued. "I was never that good at magic anyway. I almost failed Transfiguration and I'm pretty sure McGonagall hated me."

"She didn't hate you!" Tonks insisted. Then she smirked and said; "Except for that time you turned Gretchen into a kiwi-bird."

"Oh yeah", Arizona frowned at the memory. "Did you come here just to remind me of old painful memories?"

"Of course", Tonks laughed.

"Hey, what's going on?"

The two women turned around to find Callie walking over to them with her hands in her pockets.

"Callie!" Arizona smiled.

"Who's this?" Callie asked looking at Tonks.

"This is an old friend of mine, Nym…"

"Tonks!" Tonks interrupted. "You don't need to hear my awfully horrible first name."

"Okay", Callie said, smiling a bit.

"And Tonks, this is Callie", Arizona said. "My girlfriend."

"Oh really?" Tonks said with a grin that told Arizona about all the teasing she was going to hear later. "Well, you're a lot hotter than the girls Arizona dated in school."

"Tonks!" Arizona hit her shoulder, but Callie laughed.

"Are you from England?" Callie asked. "Because you've got a great accent."

"Yeah", Tonks nodded. "Nice country. A little rainy, though."

"Well, it rains all the time here in Seattle as well, so you'll feel right at home", Callie said as her pager beeped. "Oh, shot, got to go. See you later", she said and kissed Arizona's cheek. "Nice meeting you, Tonks!"

"You too, Callie!" Tonks smiled. When she was sure that Callie was gone she turned to Arizona.

"Don't say anything", Arizona groaned.

"How come I didn't know about her?" Tonks asked, pretending to be offended.

"Well, you didn't tell me about that Lupin-guy", Arizona shot back.

Tonks stared at her.

"How do you know about him?" she asked.

"A certain Weasley", Arizona smiled.

"Oh", Tonks said. "Bill?"

"Yeah."

"I'm going to punch him when I get back."

"So tell me about this Remus Lupin", Arizona smiled.

"Robbins, our surgery's in fifteen minutes", Derek said as he passed by.

"Right", Arizona said, looking at her watch. "Thanks, Shepherd."

"Oh, a surgery", Tonks grinned.

"You're not coming, you know that right?" Arizona said as they started walking. After just a brief moment of silence Arizona grabbed Tonks' elbow and dragged her into an on-call-room.

"So tell me", she said. "What's going on? What's happening with You-Know-Who?"

"Well, nothing really", Tonks answered. "But Fudge's still being a idiot and won't admit that he's back… You heard about Arthur Weasley, right?"

Arizona nodded, that part was just awful to hear. Gentle, kind mr Weasley being bitten by a giant snake. She had known the man since her first year at Hogwarts; he was the father of her friend Charlie. And, as the surgeon she was, she really wanted to help a hurt person. It killed her to not be able to look at the bites and try to help.

"Well, since then nothing else has happened", Tonks continued. "But there is something going on with Potter. There's some sort of connection between him and You-Know-Who."

"What do you mean?" Arizona asked. She didn't like the sound of that.

"Well, I don't really know", Tonks said. "No one does."

"Not even Dumbledore?" Arizona asked disbelievingly.

"If he does, he's not telling anyone."

Arizona was quiet for a long while.

"You know, I didn't come here to talk about war. I came here to think about other things", Tonks said, smiling.

Arizona grinned back.

"Ok, sure", she said. "But when you get back; keep me updated."

And with that she opened the door and the two friends walked out.

Before Arizona went to her surgery, she told Tonks to stay in the attendings' room. So Tonks was now walking around the hospital. Of course.

The muggle hospital was really interesting to Tonks. A bunch of stressed people in either light blue or navy blue clothes with white coats and long hallways and beeping noises. People in wheelchairs or on beds with wheels where driven along the corridors by people in greenish clothes. Some seemed to be in a hurry, others took their time.

She saw one woman crying silently, with her hand in front of her mouth. All Tonks wanted to do was to hug the woman and tell her that everything will be ok. But she thought that that would probably freak the woman out, so she just continued her journey through the hospital.

As much as she hated to see all the hurt people, the incredibly happy and relieved ones almost made up for it. The smiling kids by their father's bed, the hugging couples, the tears of joy, thanking God for their loved ones' life. Tonks smiled herself as she walked past these people.

"Are you lost?"

Tonks turned around to find Callie standing there.

"Kind of", Tonks said.

"Arizona is in surgery, right?"

"Yep."

"Are you looking for something?" Callie asked.

"No", Tonks replied with a shrug. "Not really. I was just exploring the hospital."

"Alright. I can show you around, if you want", Callie said and put her hands in her coat pockets.

"Really? Are you not busy?"

"No, not at the moment", Callie replied. "I have a surgery later, but I have an hour before I need to go prep the patient."

"Okay", Tonks pretended she knew what Callie was talking about. "I'd love to have a look around."

Callie smiled.

"Arizona's friends are my friends", she said. "Let's go."

Callie showed Tonks around the whole building. She also stopped and introduced her to other doctors and nurses. Meredith Grey and especially Cristina Yang made an impression on Tonks as they both seemed very uninterested and kind of rude. Mark Sloan's name also stuck, but for entire different reasons; he had looked her up and down and grinned suggestively. Callie had rolled her eyes and dragged Tonks away.

Then there was Karev, whose first name she couldn't remember, who seemed kind of grumpy. Owen Hunt was the first one to actually stop and greet her.

"He seems nice", Tonks commented as she and Callie continued.

"He is", Callie agreed. "And he's hell of a trauma surgeon. Oh look, there's Bailey."

Tonks looked in the direction of Callie's pointing hand and saw a short dark-skinned woman who was writing furiously.

"Hey, Bailey!" Callie called. "This is Tonks, Arizona's friend from England."

The doctor looked up from the chart.

"Wotcher", Tonks said with a smile. "Nice to meet you."

"And you", Bailey said as she eyed the bubblegum-coloured hair before turning back to Callie. "Torres, was Heather McKinnon your patient?"

"Um, yes", Callie replied. "Why?"

"Because she has hepatic disease. She came in this morning."

"What? I treated her not even six months ago."

Callie grabbed the chart Bailey was holding and started scan through it. Suddenly Tonks felt very much in the way.

"I'll just go wait for Arizona in the cafeteria", she said.

Callie looked up as if she'd forgotten that Tonks was there.

"Oh, yes", she then said. "Do that. She'll be done any minute."

Tonks smiled and nodded. She said goodbye to Bailey and walked down the corridor, hopefully in the right direction.

She had learned one thing that afternoon: doctors were interesting people.

Hope you liked it
