Two updates in two days :O this must be some kind of record for me!
This chappie is quite short :( but there is quite a bit of Jack in pain content in it :) so if you like that then enjoy if not then be brave :D

Jack regained consciousness only to find dark sand wrapped around his chest and covering his mouth. He kicked out weakly, trying to loosen the bonds but only succeeding in getting the sand to tighten around him.

"Now, now Jack, you mustn't try to escape." Jack froze as the familiar British voice scolded him.

"Trying to escape will only cause your friend here pain." Jack glanced around and felt his heart sink as he saw Rapunzel tied up in the same bonds of dark sand.

"That goes for you as well blondy, try to get free and Jack will suffer." Both spirits started at the new voice and watched as another figure emerged from the shadows that surrounded the dark room.

An old lady, bent double with age, hobbled over to Rapunzel and grinned down at her.

"Did you miss me flower?"

Her words meant nothing to Jack but as soon as they left her mouth Rapunzel's green eyes flew open and she tried in vain to crawl away from the old woman.

"No petal, don't try to get away, I have been searching for you for a very long time but Manny ensured that I couldn't find you, until now." The woman stroked Rapunzel's cheek and the action would have looked loving had it not been for the cruel smile that twisted her features and the fury that glittered in her eyes.

"But moth… you died when you fell from the tower?" Rapunzel sounded as though she was trying to convince herself that the words she spoke where true.

"No flower I didn't die."
Though he knew he would regret it Jack couldn't help but to add a sarcastic comment to her statement.
"Obviously"

The woman glared at Jack and her eyes blazed red before she uttered a few words while staring hard at the bonds that kept him tied.

Jack snorted in amusement; the lady looked pretty funny when she was concentrating. Then he felt it, an uncomfortable sensation that prickled at his hands. When he looked down at his bound wrists he couldn't hold back a horrified gasp at the fire that was licking around them.
Now that he was aware of the heat on his hands, the pain really started.
For a spirit of winter the heat was near unbearable and all Jack could do was squirm in his bonds and try to hold back a scream that desperately wanted loose.

"Jack!" Rapunzel's agonised cry only brought much amusement to their captors and the old lady muttered a few more words and increased the heat and fury of the fire.

Finally when he could no longer feel his hands and when they resembled lumps of burnt charcoal did the woman let the fire die out.

Although the fire died the pain in his hands remained and when he looked at them Jack's brain decided it was time to shut down.

Rapunzel stared in horror as Jack's eyes widened as he looked down at his burnt appendages before is body shuddered and his eyes rolled back into his head.

"Nicely done my dear" The tall man who was draped in shadows looked down at the unconscious winter spirit before aiming a hard kick at the boy's ribs.

Jack's limp body curled up tighter before relaxing again.

"Stop! Don't hurt him please!" Despite not having known the spirit long, knowing that he was suffering because of her and a woman she had once loved was almost more than Rapunzel could stand.

"Oh my flower, he will suffer a lot more before Pitch here kills him and there is nothing you can do to change that."

Rapunzel had to force down a sob as the shadowed man, Pitch, spoke gently to a large horse that seemed to be made from the same substance that was currently restraining her. The horse-creature came forward and in a movement that was almost kind, nuzzled the lifeless boy's hair, instantly Jack cried out, his body tensing and his limbs jerking out spasmodically.

"Ah, the power of nightmares" The man smiled as he looked down on the sleeping boy.

The three continued to watch as Jack fought some unknown horror in his sleep.

Desperate to distract the two from Jack's vulnerable body Rapunzel thought over what had been said.

"You said earlier that you didn't die when you fell, if you didn't die then what happened to you?"

This question had the desired effect as both Pitch and her fake mother turned to face her.

"I am a witch, you foolish girl when I fell I cast a spell that kept me in a stasis state although it didn't prevent me from aging as you can see… which is why I need you my petal."
Rapunzel stared at the woman who she had used to love and it all made sense in her mind, her mother had managed to keep herself from dying and had searched for her almost three centuries but had been unable to thanks to MIM but now that she had found her 'flower' she was going to use her powers again but she no longer had her hair which had contained the drop of the sun and thus her powers.

"You want to use my hair to make yourself young again but as you know Eugene cut my hair off when you tried to imprison me for the second time."

"Oh my dear your hair didn't contain your power, you contain the power, yes your hair was the easiest way for others to use your powers but it was by no means the only way."

Rapunzel cursed inside her head, she had known this after all she had healed Eugene after he had been stabbed but she was counting on Gothel not to have known this.

"Another way that your powers can be used is through your tears, which is why we have Jack here." Rapunzel looked back at the limp spirit and slowly she began to piece together what Gothel and Pitch were planning.

"Pitch will torture the winter child and when he is at death's door you will heal him and at the same time provide me with the tears that will bring back my youth and beauty." Rapunzel stared in horror at the woman she had loved so dearly.

"Then when I am young and beautiful again and the boy is healed we can repeat the entire process!"

A terrified scream pulled Rapunzel from the shock that had enveloped her as Gothel had revealed their plan.

Jack was convulsing on the floor, screaming as his nightmares reached their peak.

Pitch muttered a few words and the nightmares that surrounded Jack slunk off reluctantly and as soon as they had vanished back into the shadows, Jack's body relaxed noticeably and his terrified screaming stopped.

"He was much more fun when he was being tortured but never mind, its time to wake him up I think."

Pitch bared his strangely-sharp teeth before manipulating the nightmare sand that still hovered above Jack's head.

As Jack's eyes flickered open slowly, Rapunzel glanced at Gothel who had an eager smile stretched across her face; Pitch too had a pitiless smile etched into his features, looking back to Jack who was now blinking his eyes rapidly to get rid of any remaining nightmare sand. As Pitch's and Gothel's eyes gleamed with the promise of more pain to come Rapunzel internally begged their fellow spirits, the Guardians, Manny and anyone else she could think of to save them from whatever they would have to face next.

I said it was short :/ I'm not sure if in Tangled Gothel was actually a witch but in the Brother's Grimm story that Tangled was based on she is so in this fanfic she is a witch :)

Next update should be soon! And pretty please review! every new review makes me so happy :D
