Lucas' voiceover: Regret and forgiveness. Two emotions so different, yet at the same time so similar.

Peyton is awoken from sleep to the sound of banging from the bathroom. She pulls the covers back slowly and sleepily steps out of bed.

Peyton makes her way to the bathroom groggily, guided by the light emanating from the room.

When she reaches the doorway, Peyton freezes momentarily, her whole body turning cold and numb, terror etched in her every limb.

She is no longer sleepy, instead being pulled from her state of drowsiness by a sudden and heartbreaking fear at the sight of Brooke convulsing on the bathroom floor in front of her.

Suddenly Brooke stops seizing and Peyton lunges down towards her, gathering her friend up in her arms quickly. As she sits on the floor cradling her, tears stream from her eyes.

"Brooke?" Peyton says as she tries to wake her friend. "Brooke…"

Peyton clumsily places her hand over Brooke's neck trying to feel for a pulse…anything.

Through her fear, Peyton manages to locate the rhythmic beating of her heart and sighs.

She quickly places Brooke gently back onto the floor and runs out into the corridor, screaming for anyone to come and help her.

If you were to come to the end of your life and look back on the choices you made. Would you find something that you regretted, something you wished that you could take back?

A number of doors opened in the corridor and Lucas and Mouth both appeared from their room, sleep evident in their expressions.

The door next to Lucas' room opened and both Haley and Nathan appeared looking tired from having just woken up.

"Peyton?" Lucas questioned, rubbing at his eyes. "What's going on?"

"It's Brooke…" she said through tears.

Lucas' attention suddenly intensified as he asked Peyton "Is she ok?"

Peyton shook her head sadly.

"Someone please call an ambulance…" Peyton said sobbing as she turned to run back into her room.

Mouth ran back into his motel room to call for help, almost crashing into Skills as he did so. Lucas, Nathan and Haley, ran after Peyton.

What is regret, if not the inability to forgive yourself for the choices that you made.

Lucas ran into the bathroom to find Peyton cradling a motionless Brooke in her lap, brushing her hair with her hand and talking to her pleadingly.

"Please don't do this to me Brooke," Peyton begged, her voice hoarse from crying. "Don't leave me like this... I'm not ready to lose you yet. Please...Brooke…"

Lucas knelt down next to Peyton and placed a shaky hand on her shoulder.

"Peyton…" he said to her sadly.

Peyton glanced up to meet his worried expression before glancing towards Haley, seeing her crying as she looked at Brooke lying in Peyton's arms.

Or wished you hadn't made.

Dan sat in his office a glass of whiskey in his hand, looking at a number of photographs. The first was of him and Karen in high school, the second and third of Lucas and Nathan, the fourth of Keith.

Dan threw the pictures onto the desk in front of him and took a sip of his drink.

Regret can eat a man up inside. Consume his life until it finally destroys him.

Peyton and the rest of the group stood in her motel room as the paramedics assessed Brooke in the bathroom.

After a moment, they wheeled Brooke out on a stretcher, an oxygen mask covering her face and an IV line in her arm.

Peyton watched as they wheeled her out of the motel room, tears falling down her cheeks.

Lucas stepped up behind her and wrapped his arms around her, squeezing her tightly.

A moment later another paramedic appeared from the bathroom carrying a first aid bag and approached Peyton.

Peyton stepped out of Lucas' reach towards the man.

"Is she going to be ok?" Peyton asked him worriedly.

The man looked at Peyton closely, understanding the anxiousness she must be feeling right now.

"I'm sorry...we don't know yet," he answered her quietly. " I promise we'll do everything that we can for her."

"What's wrong with her?" Peyton asked him as she tried to choke back more tears.

"I'm not sure," the paramedic said sadly. "I noticed a cut on her forehead. Did that happen today?"

Peyton shook her head sadly.

"No yesterday," she said wrapping her arms around her body at the sudden chill that had come over her.

"Has she been drinking today?" he asked her, already knowing the answer but wanting it confirmed.

Peyton nodded.

"Has she hit her head at all today?" he asked Peyton, hoping that Brooke hadn't.

"I don't think so," Peyton answered him, "I mean, I don't know... Why?"

"She did," Mouth said stepping forward a moment. "At the bar earlier she fell onto the floor. She could have hit her head then."

The paramedic looked at Mouth and sighed.

"We're going to take her to the local emergency room. There's room for one of you to come with us if you'd like," the paramedic said understandingly as he headed towards the door. "I'm afraid the rest of you will have to make your own way there."

"I'll come with you," Peyton said through sobs as she followed the paramedic out the door and left the others standing in silence in the motel room.

If you were to die tomorrow, what decisions in your life would you regret? Would you be able to forgive yourself, or will it be something that haunts you for the rest of your life?

Haley threw her arms around Nathan's neck and sobbed into his chest as he stroked her back soothingly.

Lucas watched this as he looked back into the bathroom, running his hand threw his hair, before turning back to look between Mouth and Skills who were both standing stunned in the middle of the room.

In the ambulance, Peyton sat in silence crying, her hand wrapped tightly around Brooke's as she lay motionless beside her.
