Salvatore boarding house.

Alaric arrives.

"Elena mentioned you needed my help." Alaric said

"Yeah, we were hoping you could help shed some light on the Lockwood family." Stefan said

"Now, why would I know anything about the Lockwood's?" Alaric asked in confusion

"Well, you wouldn't. But your dead, not-dead vampire wife might." Damon said

"Isobel's research from when you guys were at Duke together." Elena said

"You said that she had spent years researching this town." Stefan said

"Isobel's research here in Mystic Falls rooted in folklores and legends but at the time I thought much of which was fiction." Alaric said

"Like that amazing vampire story." Damon said

"Aside from vampires, witches, and angels, what else?" Margaret asked Alaric

"The lycanthrope." Alaric said

"Wait, like werewolves?" Elena asked in confusion

"Are you serious? I mean really?" Margaret asked again

"No way, impossible, way too Lon Chaney." Damon said

"Is it?" Stefan asked his brother

"I've been on this planet one hundred and sixty some odd years, never came across one. If werewolves exist, where the hell are they?" Damon asked in confusion

"Why do you suspect the Lockwoods?" Alaric asked in confusion

"Because vervain didn't affect the mayor at Founders' Day." Damon said

"The Gilbert device affected me and the two of you. It also affect the mayor and it also affected Tyler. And at the school carnival, I wasn't only sensing Caroline or you two. It was Mason too." Margaret explain

"Mason was exhibited inhuman behavior when he fought with one of the carnival's workers. It suggests it's some sort of a supernatural entity." Stefan said

"We were hoping that Isobel's research could help us figure it out what it is." Damon said

"Well, all her things are still at Duke. I mean her office is still there. She's technically still missing." Alaric said

"So can we get access to it? Ric, we need to know what we are dealing with. If this wolfman thing is true, I've seen enough movies to know it's not good. It means Mason Lockwood is a real-life Lon Chaney and that little Tyler punk may just very well be Lon Chaney junior, which means Bella Lugosi, meaning me, is totally screwed." Damon said

"I guess we better get to Duke and see if Mason is a real threat or not." Margaret said


Gilbert Residence.

Margaret is putting her stuff in a bag. She senses a vampire. She opens her curtain and sees Damon in a van. He's honking.

"Margaret?! Elena?! Are you coming?" Jenna asked both her nieces

Margaret walked out her room. Her, Elena, and Stefan are going down stairs.

"Hey, are you okay?" Elena asked her aunt

"Yeah, just, men and their baggage." Jenna said

"We better get going." Margaret said

They go outside. Damon is waiting at the car. He looked Margaret.

"Call me if you need anything." Stefan said

Elena grabs Stefan by the neck and kisses him, he kisses her back. They stop kissing. Her, Margaret, Damon, and Alaric get in the car.


Alaric's Car

They're in the car, going to Duke. Damon looks at Margaret in the mirror. She looked back at him. Now her face turns towards the window.


Duke University

Alaric, Elena, Margaret, and Damon arrived. They've gone to the office.

"Excuse me, hi. I'm Alaric Saltzman, I called earlier." Alaric said

"Yes, of course. I'm Vanessa Monroe, research assistant, comparative folklore. Uh, let me just grab Isobel's keys." Vanessa said

"These are my friends Margaret, Elena, and Damon. I hope this isn't too much of an imposition." Alaric said

"Oh please, Isobel's office is right through there. Isobel was one of my first professors. I'm a grad student. She was brilliant, and one of the reasons I went into folklore. Uh, I have to ask - has there been any news?" Vanessa asked Alaric

"No, I'm afraid not." Alaric said

"It's this way. (Vanessa opens Isobel's office door, they follow her and enter the room.) I'll grab the light, feel free to look around. It's fascinating isn't it?" Vanessa asked them

"Yeah, it is." Margaret said

Vanessa leaves. Alaric, Damon, Margaret, and Elena look through the room.

"Where'd she go?" Damon asked in confusion

Vanessa comes back with a crossbow and shoots an arrow at Elena but Damon rushes over and puts himself in front of Elena to protect her. He receives the arrow in his back, grunts, and falls to the floor. Margaret pins Vanessa against the wall with her telekinesis. Vanessa drops the crossbow.

"Margaret?" Alaric said

Margaret let's go of Vanessa.


In another room.

Margaret is removing the arrow from Damon's back.

"Pull it out. I can't reach it Margaret. Just pull the damn thing out. It hurts." Damon said

Margaret removes the arrow. Damon stands up straight and shakes himself while grimacing.

"Do I have to say thanks for saving my sister again?" Margaret asked Damon

"We could talk about that or we could talk about last night?" Damon said

Damon moved in closer.

"I can't tell Elena of what happened last night." Margaret said

"Right. And I supposed I can't tell my brother." Damon said

"They'll freak. My mother, Jenna, Jeremy, everyone will freak. (They both leave the room and enter the office.) I guess you've met my half sister." Margaret said

"Half sister?" Vanessa asked in confusion

"I'm Margaret Gilbert. Elizabeth Morrow is my mother. And this is Damon Salvatore who you just shot." Margaret said

"I'd be extra nice to me right now." Damon said

"Did you say "Elizabeth Morrow"?" Vanessa asked Margaret

"Yes." Margaret said

"Come with me." Vanessa said


They're looking in Isobel's office looking for information. Damon hands Margaret a box as he touches her finger. Elena looked at her as those two are being weird. She goes back to looking.

"There's nothing in here about Katherine that we don't already know." Elena said

"Hey guys, check this out." Alaric said

Damon, Margaret, and Elena walked towards the other table.

"There's no record of werewolf mythology in Mystic Falls, but here are some records of some of the lesser-known legends. Everything from Scandinavian skin-walkers to the Maréchal de Retz. (Vanessa gives them a book with drawings.) Tonartsliitsii Metslii, which roughly translates into the "curse of the sun and the moon"." Vanessa said

"It's Native American." Alaric said

"Aztec. It explains one origin of the werewolf curse traced through Virginia. The short story: 600 years ago, the Aztecs were plagued by werewolves and vampires. They terrorized the countryside, made farming and hunting impossible until an Aztec shaman cursed them, making vampires slaves to the sun and werewolves servants of the moon. As a result, vampires could only prowl at night and werewolves could only turn on a full moon. When the full moon crests in the sky, who's ever unlucky enough to fall under the werewolf curse turns into a wolf." Vanessa explain

"Can they control the transformation?" Damon asked Vanessa

"If it were a choice, it wouldn't be called a curse. Werewolves will attack humans but instinct and centuries of rivalry have hardwired them to hunt their prey of choice: vampires." Vanessa said

"Well, if werewolves were hunting vampires, I would know about it." Damon said

"Not if there aren't that many werewolves left alive. Hundreds of years ago, vampires hunted them almost to extinction." Vanessa said

"Why would they do that?" Margaret asked Vanessa

"To protect themselves. Legend has it that a werewolf bite is fatal to vampires." Vanessa said

Alaric, Elena, Margaret, and Damon look concerned.

"Oh..." Damon said


Elena is looking in a box and finds a picture of Katherine. Margaret kept looking through the box

"Hey, have you done any research on doppelgängers?" Elena asked Vanessa

"Well, the word means a lot of different things to different cultures, but typically a doppelgänger is a living, breathing double of oneself." Vanessa said

"Did Isobel have anything that explained the link between me and Katherine?" Elena asked again

"That's all she had on Katherine, unfortunately, but I can tell you that doppelgängers usually torment the people they look like, trying to undo their lives. It's not exactly uplifting." Vanessa said

"And more things we already know. Just...I want to know why we look alike." Elena said

"Crap. I mean more pictures of my mother. And...(Margaret touches a pentagram. It sizzles on her hand as she groan in pain.) What the hell?" Margaret said

"Are you ok?" Damon asked Margaret

"I'm fine." Margaret said

"Has your mom's memories been erased?" Vanessa asked Margaret

"She was killed by Katherine in 1864. Stefan and Damon knew her. She was brought back to life. Had me, her memories been erased of mine and Elena's father. And a few months ago I found her. Told me about being a human/angel hybrid." Margaret explain

"Did she tell you another name for it?" Vanessa asked again

"No idea what you mean by that. (Vanessa grabs another book. She puts it on the table. She flips the pages and stopped.) Celestial court?" Margaret asked in confusion

"That's what they called themselves. Since you're blonde. They would call you the blonde guardian. The Celestial Court is the corresponds to Heaven. Protect themselves from the supernatural creatures. The angels have a few powers on their own when it comes to their wings. But with a human/angel hybrid. I don't know." Vanessa explain

"But I'm part angel. I can move things with my mind and hear peoples thoughts. I can sense vampires, witches, and now we heard about werewolves." Margaret said

"But you're also part human. With wings. It can't be possible." Vanessa said


Outside.

Both Margaret and Elena are at the car. Margaret can't open the car door. Damon arrives.

"Allow me." Damon said

Damon unlocks the car. Him and Margaret looked at each other.

"Thanks." Margaret said

"Can we just go?" Elena asked

Both Margaret and Damon stopped looking at each other. He gives Elena a book.

"You didn't dig deep enough." Damon said

Elena looks at the book. "Petrova" is written on the spine.

"Petrova". I saw this on a shelf." Elena said

"Katherine originally came from Europe. Petrova was her real name. Katerina Petrova, to be exact." Damon said

"How did you know that?" Elena asked Damon

"Back when, I saw it engraved on an old heirloom." Damon said

"Thank you for the book, Damon." Elena said

They get into the car.


Gilbert Residence.

Elena, Margaret, and Damon are on the porch.

"Road trips work well for us." Damon said

"You two been acting weird all day." Elena said

"What do you mean?" Margaret asked her sister

"On the road trip. The university. I need to know the truth. What is going on? (Both Damon and Margaret looked at each other as she shakes her head. Meaning, "Don't tell her.". Elena put the pieces together.) You two slept together, didn't you?" Elena asked both her sister and Damon

Margaret looked guilty. Elena ran inside.

"Margaret..." Damon said as Margaret cuts him off

"Shut up! (Margaret runs after her sister upstairs and enter her room.) I can explain." Margaret said

"You slept with Damon." Elena said

They started arguing.

"I don't see what the big deal is." Margaret said

"He's seducing you." Elena said

"No he's not." Margaret said

"You make good choices. Smart choices." Elena said

"And Damon doesn't? He's trying to be good. Ric is starting to be friends with him." Margaret said

"What about that time when he turned Vicki?" Elena asked her sister

"You didn't just go there." Margaret said

Margaret shakes her head and storms out of her sister's room. Elena dials Stefan's number and calls him.

"Hey." Stefan said

"We have a problem." Elena said

"Has Damon been messing with Margaret again?" Stefan asked Elena

"Actually it's the other way around. They slept with each other." Elena explain


Salvatore Boarding house.

Damon opens the door and closes it.

"Hey there brother. (Stefan vamp speed to his brother and punched him in the face.) Ok. I'm guessing Elena told you." Damon said

"I tried to tell you to stay away from Margaret." Stefan said

"She can make her own decisions. Not you or anyone can do anything about it." Damon said

Stefan tackling his brother and start to beating the crap out of him.
