"Okay class today we're going to learn about sun shadows, that is when you can measure the sun's shadow on any given object…" the teacher's voice is fading as Mercedes is half listening.

She can't concentrate and she swears she sees Emily Jones just walk through the hallway. So, to investigate further, she gets up from her desk and walks out of the classroom. At first Mercedes can't find her so she walks around the hallway calling out hello. Mercedes finally finds her and follows her out the school doors and into the woods. Mercedes looks at her surroundings and becomes very confused, but she continues to follow Emily.

"Please help me," says Emily.

"Who are you?" asks a scared Mercedes.

"I'm Emily. You know that, you found me."

"Why do you look like me?"

"Kurt's not the only one with a doppelganger."

"What? Where am I?"

"This is where it started and this is where it has to end."

"No, this isn't real." Mercy tries run in every direction she can, but Emily just follows her.

"Help me."

Mercedes jolts out of her chair as she woke up from her dream and everyone around her looked at her crazy. "What are looking at? Turn around." Then Mercedes turns to see Emily and she screams.

Mercedes wakes up again in the woods, lying where Emily told her where it began and where it had to end.

"Have you've even spoken to Mercy?" asks Kurt to Quinn as they were walking toward the school's entrance.

"No, because I'm mad at her and she needs to apologize to me first," explains Quinn.

"Why are you so pissed at her anyway?"

"She's a thief, that's why. I gave her my necklace and she refuses to give it back."

"Alright, well I tried; I'm officially out of it."

"Good, your turn. Where's Blaine? Have you talked to him?" asks Quinn as she and Kurt stop at his locker.

"He's avoiding me."

"Why?"

"It's complicated." The bell rings for class. "I'll see you later."

"Bye." Sam walks past Quinn. "Hey!" And he ignores her.

Kurt walks in to his History class, hoping to see Blaine, but to no avail, Blaine wasn't there. But Mercy arrives and keeps her head ducked down and Kurt notices. He mouths, "Are you okay?" to her, but she just shrugs off the question. Along with Mercedes, the class' new history teacher arrived.

"Hello class, my name is William Schuester, your new American History teacher," announces Will. "Now, I know that Schuester is a mouthful, so I'm giving you two options; Will or Mr. Schue."

"Rise and shine! You'll be late for school!" shouts Puck as he pulls the covers off Blaine.

"What are you doing?" questions Blaine as he gets out of bed.

"Peace offering. Alright, I'm sorry."

"Get out of my room."

"I got the town off our back and it was for the greater good, but I'm sorry. And to prove it, I'm not gonna feed on a human, for at least a…week. I'll adopt a Blaine diet."

"Look I realize killing your closest and oldest friend was beyond evil, yet somehow, it's worthy of humor," says Blaine mocking Puck.

"Are you mocking me?"

"Yes, Blaine, now that the secret society of vampire haters is off our back I can go back to my routine of, 'How can I destroy Blaine's life this week?'" says Blaine in a sarcastic tone.

"And I can go back to sulking and Kurt longing."

"And I will finally reveal the ulterior motive behind my evil and diabolical return to Lima."

"Yeah, I'm done with this game. 'That's just like you Puck, always has to have the last word'," says Puck.

"And then I ended up at the remains of the old church before I woke up back in the woods," says Mercy as she explains her dream to Kurt at lunch.

"And you always see your ancestor, Emily?"

"Yeah."

"Huh."

"Do you believe in ghosts?"

"Two weeks ago, I'd say no, but now…?"

"I think I'm being haunted."

"I don't get it. Why Emily?"

"Grams said she was alive back in the Civil War days and the crystal was hers; the witches' talisman."

"And it all started when you found that necklace?"

"I think she's using it to communicate with me."

"Okay what does Grams say about it?"

"I can't call her. She's gonna tell me to embrace it. I don't want to embrace it; I want it to stop."

"Hey, Mr. Schuester, I'm Finn Hudson, you wanted to see me?" asks Finn as he arrives in his classroom.

"Yes, I did Finn, have a seat," says Will. "Do you know that your old teacher had a jackass file? I'm serious, he even typed out a label. It has all the troublemakers in here, but really, it's a composition to you." Will gets up to throw the folder away. "But don't worry about it, I'm not him. Clean slate. Now, let's talk about grades."

"I know it's been a rough couple of months, but I've been trying to turn them around," explains Finn.

"Yeah, I saw that but the problem is that we're half way through a semester and you're failing, that's pretty bleak. You know this is part where you say to me, 'What can I do to change that?' Well I'm glad you asked; what do you feel about extra credit?"

"Yeah, yeah totally whatever."

"Good, write me a paper then."

"Okay, about what?"

"History, pick a topic and keep it local and no Wikipedia regurgitation. These old towns have a lot of rich history. So just get your hands dirty, make it sing and you're back on track. Deal?"

"Yeah deal," Finn says excitedly.

"That's a cool ring."

"Uh, thanks, it was my father's; a little garish, but still a family heirloom." Finn got a little confused since Mr. Schue was using big words. "You've got a week."

"Hey," says Sam as walks pass Quinn.

"Hey. Wait, what is that?" asks Quinn and she demands an explanation.

"What is what?" asks a confused Sam.

"The 'hey'; that is twice, those are two 'hey's. Do you have any other words in your vocabulary?"

"What's wrong with 'hey'?"

"It reeks of awkward subtext. You spent the night in my bed. There was cuddling and you snuck about before dawn so you wouldn't have to face me." Sam looks very confused. "Which I must say, is a total lame guy move; which I did not appreciate. Now with the 'hey's? Seriously?" Sam wants to stop Quinn, but her mouth keeps moving. "I mean I may have been some insecure, pathetic mess after the party, but do not mistake that for me being a push over, because I do not let guys mess with my head anymore."

"I heard your mom come in that morning. I didn't want to get you into trouble so I snuck out the window before she caught us."

"You went out the window? Another lame guy move."

"Your mom's the Sheriff and as for the 'hey's, I'm pretty sure it's what I've said to you since the first day of first grade."

"Oh."

"Trying to overthink a harmless situation? Lame girl move." And Sam walks away leaving Quinn stunned.

Kurt walks out of the school to see Blaine sitting on top a table, waiting for him. Blaine half smiles to see if Kurt would go near him.

"Hi," says Blaine.

"You weren't in class, I was worried."

"Yeah I got your messages. Sorry I didn't get back to you, but…what I need to say shouldn't be over the phone."

"A simple, 'I killed my brother' text would have sufficed."

"I didn't kill my brother, even though he deserves it. He has you to thank for that."

"So, what did you want to tell me?"

"I won't be coming to school anymore. I need to back off and keep my distance. It's the right thing to do."

"Back off from school or from me?" Blaine doesn't need to answer him, Kurt already knows. "Thank you for telling me."

"It's better this way."

"Yup I got it," Kurt snaps.

"You're angry, that's good. It'll be easier if you hate me." Blaine walks away, leaving Kurt trying hold back his tears.

Mercedes is walking to her car, minding her own business, until Puck appears in front of her and she nearly screams.

"Okay this is your last chance."

"If you don't leave me alone, I'll scream," says Mercedes as she was trying to get away from Puck.

"Don't do that, let's stay on point. Listen, I want my crystal."

"You can't have it."

"Well, I can't take it, but you can give it to me. Look, I'm trying to help you here, Sexy Mama."

"I don't want your help and don't call me 'Sexy Mama'."

"You do want my help and you don't even know it. You know why, Mama? Cause you've stumbled into something that you need to stumble out of."

"Just leave me alone or I swear I'll- "

"Oooh, no threats. Look, (a) you hurt me last time, (b) I wish you no harm; believe it or not, Mama, I want to protect you," says Puck as he touches the side of her face. "Let me help you get Emily off your back."

"How do you know about her?"

"I know a lot of things and I know more about that crystal than you do. And you look exactly like her," whispers Puck in Mercedes' ear. "And know what she's using it for, to creep inside of you." Puck touches her heart. "Your heart is beating fast. Am I making you feel something? Are you drawn to me?"

"N-n-no," Mercedes answers shakily.

"You know, Emily and I had some fun times. Maybe, you and I can have history repeat itself. And I know you're scared, as you should be. I'm only trying to help you here Mama. So, next time she comes out to play, you tell her that a deal's a deal, and make sure you say from her lover."

"But how can you know Emily?" asks Mercedes. Puck ignores her and opens Mercy's car door and closes it behind her after she shakily gets in.
