Santana knocked on her grandmother's door, the hour drive out too Allentown gave her enough time to think about what her and Brittany spoke about that morning.

"What was it like, when the plane started malfunctioning?" Santana's hand moved over the blonde's torso as her head rested on her shoulder.

"It's all hazy, like someone doesn't want me to remember, like when you have a dream and you can remember bits and pieces but you can't remember how they all fitted together. I remember a figure being sat next to me but it's just a blur, I was the last person they ever saw and I didn't even know their name let alone whether it was a woman or a man, and I remembered them screaming about their children then everything goes blank, I can't remember anything after that."

Recollecting their conversation drove a shiver down Santana's spine, Brittany was so adamant that there was someone sitting next to her on the flight, yet there was no record of this passenger.

There was no baggage, no body, and no ticket information; the airline had no record of an eighty second passenger on board. Her thoughts didn't query why Brittany would imagine it; her thoughts queried why the airlines were lying about this missing passenger.

Santana peered through the window of the house after her third knock went unanswered, a defeated sigh escaping her lips as she placed the flowers at the doorstep.

She walked off the porch towards the car, the man standing beside the driver door making her skin crawl.

"Who lives here Dr Lopez?" Mr Hummel stared into Santana, her rage quickly building as she realised that she'd been followed.

"Are you following me?!" her voice trailed off with rage and disgust the closer she edged towards the man.

"Is spending the night with your patients a regular part of their therapy?" Santana looked to the floor as the weight of the world seemingly fell on top of her, "your credibility is on shaky ground Dr Lopez."

Mr Hummel turned to walk away, the briefcase that always seemed to draw Santana's attention in his hand.

"I know about the extra passenger Burt, come on? Just between us girls, off the record, why is the airline covering it up? Why are people disappearing Burt!"

Mr Hummel turned, his eyes not quite meeting Santana's "I have no Idea what you're talking about Dr Lopez and please, call me Mr Hummel"

Santana walked towards the man stood over the pier, she knew that if there was one person she could turn to in a crisis it was him.

"Will, there's a man following me and my patients, two men actually. Hummel from the airline and another man who shows up around my patients and meetings, he disappears as soon as someone notices him and I think he's from the airline, I don't know what I'm doing, I'm out of my depth here, there's some kind of cover up going on and my patients are disappearing and I-"

"Santana slowdown, whose missing?!" Will lead Santana towards the bench where they both sat.

"Quinn, Rachel and Mercedes are missing, they've been missing sessions" her voice trembled slightly as the seriousness of everything dawned on her.

William stared intently at Santana "they're missing or they're missing sessions?"

Santana stumbled over her words as she ran a hand through her thick dark hair "I'm not sure Will"

"Santana just because they're not at the sessions doesn't mean they are in trouble?" Will mimicked Santana's motion running a hand through his own thick hair.

"What about Brittany Pierce how is she doing?" Will cocked his head to the side as Santana's face seemed to drop.

"What? Oh, aha, well, yeah, she's er, doing great? She's responding well to-" Santana shook her head slightly as she gazed out over the pier.

"Santana what's going on?" Will leant back against the bench, resting his elbows on each side.

"I crossed a line with her Will, an ethical line, our relationship is more personal than it should be."

Will bit his cheek and glared at the Latina, nervously laughing as he repeated the last of her sentence.

Santana finished the conversation with Will, feeling arguably calmer than what she did at the beginning as she made her way to Mercedes house, deciding that she was going to go and check for the answers herself.

Santana went to knock the door, but it was already open. Her head peeked round the frame as she took in how well kept the home was.

"Mercedes it's Dr Lopez, I mean Santana."

Santana walked through the hall, the only thing out of place in the meticulous home was the photo that hung crooked on the wall. Something about it made the skin on Santana's back crawl, it was a photo of the man who sat at Mercedes hospital bed the first time she met Brittany.

"Mercedes you're really worrying me, are you here?"

Santana looked around the living room, the pile of papers on the coffee table seeming to draw her in, a picture of Sam sat on the mantle, seemingly watching over each of the Latina's movements.

Santana picked up the closest newspaper clipping, a picture of an aeroplane marked the page.

"Airline Besieged by Maintenance Problems"

Santana looked around the living room one last time, looking for any signs of life before finally exiting the house, the feeling of intrusion becoming all too apparent, she breathed a sigh of relief as she stepped into the cool air outside before seeing the figure across the road, the same man who seemed to flee when she noticed him was now running. Except he was running away from her, he seemed to be running towards her.

She ran to the car, her feet barely carrying her fast enough as the man followed in pursuit, "Dr Lopez please don't go, I need your help."

Santana paused for a second, before cautiously turning around, seeing the fear in the otherwise strapping man's eyes. "Who are you?"

The man looked at her, his bottom lip seeming to tremble slightly "I- I- don't know, the lady who lived in that house seemed familiar so I thought maybe if I could speak to her, or any of the other people in the group they could help me work it out. But she wouldn't come near me; I can't remember anything since the accident."

Santana's jaw dropped as she seemingly witnessed the scene unfold, "wait a second, you saw the accident?"

The man ran his hand over his thick dark slick back hair "I didn't see the accident, I was in the accident."

Santana's throat grew tight as she choked on her words "you were on the flight?"

"Yes, one moment I'm sitting there, the next there's an explosion and were hurtling to the ground, what the hell happened" tears began to fall down the man's chiselled tan face as Santana got out of the car and edged closer towards him.

"It's okay, I'm going to help you, have you told anyone else about this..." the man shook his head in response, "…I'd like you to come with me, have you got a wallet or a work ID on your person? Anything that can help us identify you?"

"Will its Santana, call me as soon as you get this, I've found another survivor from the flight. Call me back." she hung up her cell phone and turned her glance to the man sat in the passenger's seat, his head cocked as he gazed out the window.
