I'll admit, the idea of this fic isn't mine. Especially given the fact that I really liked Freaky Friday:P. But I just thought that with Nikola and Helen things would get interesting. :P. I hope you'll like it :P. And if you ever feel sad… remember that just because sometimes you can't have something entirely, it doesn't mean that it will ever cease to be partly yours. Just saying.

"Magnus, wake up!" The banging at the door refused to stop and Nikola just wanted to kill Will for that. He had been unusually tired the previous night and the last thing he needed was to wake up early. Wait. Why was Will banging at his door, calling for Helen? It didn't make any sense. Unless…

With a great deal of effort, Nikola opened his eyes and discovered that he wasn't in his bedroom. But he knew the bedroom he was in. It was Helen's. No, that wasn't possible. The only way she would have let him in her bedroom without shooting him was if they… But he didn't remember a thing. And he was completely sure that he would never forget a night with Helen. Something wasn't right.

"Magnus, wake up! I have to talk to you!"

"She's not here, Junior! I'd love to know where she is, but she is not here!"

On the other side of the door, Will rolled his eyes. Great. He knew that spending that much time with Tesla will make Helen insufferable sooner or later. Now she called him Junior too?

"Very funny, Magnus." He said muttering. "Can you please get out? Someone wants to talk to you."

"I told, you, I'm not-" Nikola stopped mid-sentence when he saw his hands. Actually, they weren't exactly his hands, they were… No, that was just impossible. He almost ran to a mirror and just couldn't believe his eyes.

"Holy mother of-"he almost shouted.

"OK, that doesn't sound right. Whatever it is, Magnus would have said bloody hell." Will said jokingly. The door opened and he saw his boss, angrier than she had ever been and he knew he was in trouble. But why? Just for waking her up?

"Where is Helen?" his boss asked.

"Helen?" Will had never been more puzzled in his life.

"Yes, Helen. Helen Magnus. The woman with the hot British accent who also happens to be your boss. Where is she?"

"Are you in the mood for jokes today, Magnus?" Will asked. "Listen, I know you are in a bad mood because I woke you up, but Tesla is at the door. He requested he immediately speak to you."

"Listen, you punk, Nikola can't be at the door, because-" Nikola stopped. Right. He needed more time to get used to the current state of affairs. If he was lucky enough, then the one at the door was the one he needed. "OK, well if Nikola wants to see me, I should go and welcome him, shouldn't I?"

Will rolled his eyes again before following his boss to the doorstep. This was the craziest morning he ever had at the Sanctuary. And that said a lot. He watched Helen as she almost ran to open the door, praying that she won't jump in Nikola's arms. She didn't, but what she did was far more surprising.

"Helen?" Helen asked.

"Nikola?" Nikola replied.

"Apparently so, I'm afraid."

"Listen, Magnus, can you please explain what the hell is going on here?" Will interrupted them.

" Yes, I can."

"Not you, Tesla."

"I am not Nikola. I am Helen. He is Nikola." Nikola said, pointing to Helen.

"Great. So now you're both making fun of me. I mean, I get that Tesla would do something like that, but you, Magnus…"

"Listen, Will, this is not a joke. I am Helen Magnus. You have to believe me."

"Hey dude, what happened?" Henry said, entering the room.

"These two are trying to pull a stupid prank on me." Will said muttering. "Magnus says she is Nikola, Tesla says he's Magnus."

"Dude, that is so Crusade." Henry said with his geeky grin.

"What?"

"They switched bodies. Magnus' conscience is inside Nikola, and viceversa."

"Thank you. See, honey? I told you he's a smart one." Nikola said.

"Yeah right." Will still wasn't buying anything.

"Go ahead. Ask me something that only Helen would know." The one with Nikola's body said.

"How old are you?"

"That is not something you ask a lady, but if you insist… I'm 274 years old."

"Helen… what were you hiding from me? Last time I checked, you were only 5 years older than me."

"Long story, no time."

"Of course. Well then, I have to say, you look wonderful for your age."

"Thank you. More importantly, how did we get here? And Nikola, please, next time pick pants that are your size. These are stretchy."

"They are my size, Helen. They don't stretch in the back, do they?"

Helen couldn't help a guttery grin. She just wished she wasn't blushing-well, that Nikola's face wasn't blushing.

"Are you saying that you didn't take a peak in the mirror at yourself since this happened?" Nikola couldn't help asking.

"Well excuse me if I was too busy with getting back at the Sanctuary and finding out what happened. My Sanctuary."

"Well, I guess that makes you the good girl and me the bad boy huh?"

"Nikola Tesla. Did you watch me naked?"

"I watched myself naked, Helen. I don't think it is forbidden to do so. Sure I happen to be inside your body but…"

"You are so dead."

"You can't kill me. Vampire, re- Crap. What now I can't morph anymore?"

"I think not. But I can." Nikola watched terrified as one of his talons was pointing at his neck, while he stared in his own blackened eyes. "If you watch me again naked, Nikola, I swear I'll…"

"Without your permission that is."

"You'll never have it."

"Keep telling that to yourself darling."

"Hey, guys." Will said. "I don't want to interrupt you, but can you please explain what the hell happened ?"

"Whatever you may think, Helen, it's not my fault. Well, not entirely. Not juridically speaking."

"Nikola…. Spill it out. Now."

"Well, remember that stone we found yesterday?"

"Yes, the wishing one. The one we brought in the lab. You don't actually think it worked."

"It did. But not as I wanted."

"Nikola… what did you wish?"

"It's not important."

"Nikola, I am trapped in a vampire's body, I will probably feel the need to drink blood soon enough, I am not in the mood for stalling."

"OK,OK. I wished to get inside your pants. Apparently that stupid stone doesn't understand English slang."

"It's 2000 years old, Nikola!"

"Yeah, that too. My bad."

"Nikola!"

"Listen, there is no harm done, alright? We'll just go inside the lab, wish it back to normal and we're done."

"Wait, what stone?" Will was still puzzled.

"I'll explain you immediately, now I am too busy getting Nikola out of my pants." Helen said, stressing each word nervously.

"You know, I would have given anything to hear that phrase out of your mouth in a different context."

"Shut up."

"After you my dear." Nikola said after they got into Helen's laboratory, all four of them facing the stone.

"I think I should do it. You may have had only a single wish."

"Be my guest."

"I wish none of this happened and we would both get back into our own bodies."

"Sorry, but it didn't work."

"Yes, I can see that. Well if you think you can do it better…"

"I can do anything better than you, darling. I wish I was in my body again."

"Did it work?" Henry asked with hope in his eyes.

"Bloody hell!"Nikola said.

"Prokleti." Helen muttered under her teeth.

"Apparently not, Henry." Will sighed.

The four of them watched puzzled as 21 words appeared on the stone. Clothed togs, chest old tog; kid into you, I wild out beans, give it on; Ebony woke four, inlay neon owls.
