I am playing around with the timeline. This is an AU. Two wesen that were in season two will be making an appearance and in a different way than they did in the show.
Something that Adalind knew their friends would not want to know was, just what all really needed to be done when she gave Nick the potion that would make it impossible for any being to take away his abilities.
The only wesens who had the ability to take away a grimm's powers were hexen and zauberbiest. Only they possessed the abilities to manipulate matter and nature. And one would have to be very powerful, as well as extremely motivated to risk getting close enough to a grimm to pull off the task.
Becoming physically intimate with a grimm was the only way of taking, restoring and or protecting their powers.
When they were in Adalind's apartment and locked the door, the hexenbiest turned to Nick and pressed her lips to his. She wanted to make him feel relaxed, and not feel as if he had to force himself to participate.
But she really should have known. Her man's libido and desire for her was a constant thing. The very moment Adalind showed interest in being with him, Nick was rock hard and eager. He gathered her in his arms, pressing her tightly against his body and returned the kiss passionately.
Still holding the jar with the potion in it, Adalind whispered to Nick to take them to the couch. The jar was set on the coffee table, and Adalind sat herself on Nick's lap, straddling him. She ran her fingers through his hair. He roamed his hands firmly over her back. Their lips moving together with hungry need.
"I need to give you your protection potion, baby." Adalind purred.
"Later," Nick argued. "I need you, now."
Adalind explained to him with a giggle, "The potion is to be administered while we make love."
She levitated the jar to her hand.
"While you're inside me, I'll spill the spiced wine into your mouth. It will take full effect when you spill your seed inside me."
"Will we make a baby?" Nick asked as his hand moved over Adalind's belly with reverence.
"No." she told him gently. "I take a potion to prevent unplanned pregnancies."
Seeing the slight disappointed look on Nick's face, Adalind felt the need to assure him. "When we're ready, I'll stop taking the potion and we'll have beautiful babies."
"I want a little girl that looks just like you." Nick demanded, cupping Adalind's face and taking her lips in a ravenous kiss.
Telling him she liked that idea would wait for another time. Instead she focused on getting his clothes off of him. She set the potion on the couch next to them, freeing her hands.
Clothes off and naked bodies pressed together, Adalind still sitting on Nick's lap, this time with his erect member quivering with need at her entrance. Adalind picked up the potion, "When I lift myself up and slide your shaft inside me, I will spill the first mouthful into your mouth. You have to swallow it. I will repeat the process, moving my hips over yours, until the jar is emptied. You can not come until it is complete."
It was one of the reason's the potion was so difficult to create. Few men could hold back when being pleasured by a hexenbiest. But Adalind had faith in her grimm. She knew from experience just how long he could last.
Still, she kept the pace slow, at first. Though Adalind found that she was having a difficult time keeping focused on the task.
Somehow, by some miracle, the jar was finally empty, allowing Nick and Adalind to fully lose control.
Nick wrapped his arms tightly around Adalind, thrusting his hips up as she ground down. Their constant moans were muffled because they could not bear to move their mouths away from the other. His seed erupted inside her as her walls contracted around him. Waves of euphoria washed over them, completing the spell.
Adalind collapsed onto Nick's chest. Her body so blissed that sleep claimed her quickly. Nick simply stayed and held her, stroking the golden silk strands of her hair.
It was soon discovered that they had made and consumed the protection potion at the right time. The royals had a strong interest in Nick. They believed that a grimm on their side would tip the scales in their favor. And so they were sending out beings to obtain him, by any means necessary.
One royal thought the best way to obtain Nick was to seduce him. A wesen called a musai was sent to make Nick become obsessed with her. However, that backfired tremendously. The royal did not realize that a musai kiss could be deadly. Those with an intense and passionate nature could become so obsessive that they would turn violent towards anyone who was a threat to the bound between them and the object of their obsession.
Luckily, for everyone, the pull of the musai paled in comparison to the hold Adalind had over Nick.
Nick had returned home and told Adalind about an elf like being you kept trying to kiss him. He assured her he did not allow her to. He just thought it was strange that a total stranger would be trying to kiss him.
Adalind knew the being he was referring to, created a special potion and asked him to take her to where he saw this woman.
"She told me she would be staying at the Crowne Plaza hotel, in case I changed my mind about meeting her."
Adalind did little spellwork on the phone, making the call untraceable. Nick called the musai and asked her to meet him at a nearby diner.
The musai, not realizing the grimm was in the company of a hexenbiest, tried to entice Nick to follow her into the shadows of the alleyway next to the diner.
Adalind took the lid off of the potion jar and threw it's contents at the other woman, who screamed in shock, and then in pain.
"Your kisses won't be making anyone else your devoted slave." Adalind told the woman with a sneer.
Once word got to the royals that the grimm had a powerful hexenbiest as his companion, they decided that the way to obtain him was by brute force.
Sean Renard had gotten word that the royals were trying to take Nick. He did not know everything they were up to, but he knew they were going to use every resource they had. Sean really did not like the idea of his half brother, Eric, succeeding where he had failed. He knew that if they got Nick, there would be nothing he could do to claim what he believed to be his rightful place.
Out right moving against the royals was akin to suicide. If it was obvious he sabotaged their plans, they would certainly try to kill him. At the very least, he would never have a seat among the royal families.
Sean decided that the best thing to do was make the grimm useless to the royals.
"A jinnamuru xunte should work nicely." He thought to himself.
And that made him the second being of royal blood to underestimate Nick.
Renard thought he was clever by telling the blow fly wesen to attack Nick while he was investigating a case with Hank.
"Make sure his partner is occupied somewhere else." Renard had warned.
The jinnamuru xunte waited for the dark skinned detective to walk into a coffee shop, getting drinks for himself and his partner. The wesen pretended to need help, looking disheveled and in hysterics.
When Nick got out of the car, he saw the man quickly woge into a large fly and spray him with something that immediately began to burn his eyes. He was able to pull his service weapon and get one good shot off before everything went completely black.
He could hear Hank calling his name and felt him at his side. But he couldn't see anything.
Hank immediately called Adalind. Knowing they were dealing with a wesen, he was sure that the hospital would not know what to do.
He was right.
"I know this wesen." Adalind explained. "Get him to the spice shop right away. Do not let him close his eyes. Try to have him face toward a source of light."
Hank got Nick into the car, turned on his police issued flashlight and helped Nick shine the light into his eyes.
Hank called Wu and told him to run an APB on the make and model of the car he saw Nick's attacker get into.
When Nick and Hank arrived at the spice shop, the others, having been told of the situation by Adalind, were all there and looking understandably concerned.
"Dude, Adalind said that the guy sprayed tiny worms into your eyes!" Monroe blurted when he saw Nick. "You can't wash them out because they latch on and dig in! And the worse part, that they actually eat your eyeballs. If we don't find a way to get them out, you will never be able to see, again!"
"Monroe!" Rosalee said harshly, trying to get him to stop.
"What? I thought he would want to know. I would want to know." Then thinking it over, the blutbad realized, "Maybe not. I'll shut up now."
Nick was guided to a chair and a lamp was turned on, the light focused to shine right in his eyes.
As he sat there, Nick noticed that all of the noises in the room seemed to come in clearer. He could make out a fly on the skylight above him. He could hear every page of the books everyone was looking through being turned.
Hank's cell phone rang. It was Wu saying they had found the car. It had been reported stolen by the owner one hour before Hank called in saying Nick was attacked. The sergeant also said that they found blood inside the car. It seemed Nick had been able to wound the guy before going blind.
When Hank ended the call, Nick said, "That was Wu, they found the car and they found blood in the car."
"How did you know that?"
Instead of answering him, Nick announced, "Rosalee found something."
Surprised, everyone turned to the equally astonished fuchsbau, who said, "There is a cure but we need one of the eyes of the jinnamuru xunte to make a paste, and then apply it to Nick's eyes.
"If the guy is wounded, I can track him." Monroe said, eyes turning red.
The group loaded into their cars. Hank and Monroe tried to make Nick stay behind, but Nick protested and the ladies said the sooner the paste could be put over the eyes the better.
Nick was still told to stay in the car while Hank and Monroe went into the house Monroe assured he could smell the blow fly wesen the strongest.
But Nick could hear that they were unable to find the being. He could also tell exactly where his wesen attacker was.
He shot out of the car and ran into the house, ignoring the shouts of both Adalind and Rosalee.
He followed the buzzing noise he recognized to a room. He made sure to focus, drowning out the shouts and questions from his friends. He heard something bang on the wall behind him and ignored it, knowing that it was a misdirection.
The buzzing got louder and Nick could feel a presence moving toward him quickly. Reacting quickly, he blocked the hit and grabbed onto his attacker's arm. The wesen tried to knock the grimm to the ground but Nick turned them. He was able to get his legs around the man's neck, cutting off his air and rendering him unconscious.
When he heard the others run into the room, Nick shouted, "He's unconscious. Get his eye."
Adalind and Rosalee quickly jumped into action, scooping the woged eye out with a large spoon then smashing it in a bowl with the other ingredients, making a paste that they spread on a strip of cloth.
"Dude, be glad you're not seeing this." Monroe commented, feeling sick.
"This might sting, but you need to keep your eyes open." Rosalee warned.
Adalind tied the cloth around Nick's head. He flinched, the paste stinging like he had been warned, but he obeyed orders and kept his eyes opened.
When the blow fly wesen had regained consciousness, and after he was done screaming about his missing eye, he was threatened by a hexenbiest, a blutbad and a fuchsbau into revealing why he had attacked Nick.
"The Prince of Portland doesn't want anyone from the royal families to get their hands on the grimm. He thought that blinding him would make him useless to the royals."
The wesen was told to leave Portland. And if he ever showed his face again, he would lose more than just his eye.
The next day, Sean Renard was shocked to see Nick Burkhardt walk into the precinct with a smile on his face and his sight perfectly intact.
"Hey Burkhardt." One officer yelled. "I heard some creep sprayed some stuff in your eyes. Blinded you. You going to try to bring him in? Arrest him for assaulting an officer?"
Renard knew that if Nick could see, he must have found the wesen and was able to make a healing paste.
"Well you know what they say about an eye for an eye." Nick shot a glance at his captain through his office window.
