A/N It has been suggested that maybe Joyce should have a little extra herself. And I could see Joyce wanting to share this new adventure with Buffy as much as possible. It's also been suggested that Joyce have something separate from Buffy that would still allow her to share it. I've come up with a way that fits into Grimm mythology but is my own creation for the sake of this story.

"Let's start with the cleansing." Amy suggested. "The soul bonding will go much easier if there's nothing demonic to interfere with it."

"That makes sense, as much as any of this makes sense." Joyce agreed.

In a bowl Amy combined rosemary, sage, eucalyptus oil and whale oil and once again set it in front of Buffy and ignited them while reciting a cleansing spell. "Elmo, Dama, Sayto, Mundo!" A small pillar of fire shot up from the bowl.

"Ohhh." Buffy said and fell back against the couch as a wave of dizziness washed over her and something dark was pulled out of her and into the fire.

"Well, I'd say that was effective." Cordelia observered. "Because I would certainly describe that as dark."

"I agree." Xander said. "I'm not seeing anything dark in her anymore. Do you still feel strong, Buffy?"

"No, I always have this energy, like electricity in my veins, it's gone. Mom, are you ready for the soul bonding part?"

"Yes, but are you sure you're alright?" Joyce asked anxiously.

"I don't like this feeling, it reminds me of what Giles did to me and how helpless I felt. But I also don't like knowing there was something demonic in me. Everything else aside, I'm glad that stuff is out of me."

"Then I guess we should do the soul bonding." Joyce decided.

"Stand facing each other." Amy instructed. "With Magic you have to remember it's about intent. Joyce, it's your soul that's going to be used to provide Buffy with protection. Which means you have to provide the intent, the reason for why you're doing this. Picture it in your mind, your reason and hold on to it. Buffy, relax and accept what she's offering you."

Joyce sorted through her memories, her feelings and found it. Her reason. The first moment she'd realized she was a mother and that her baby needed her and her resolve to be the mother her baby needed. She held tight to that feeling, that memory, that resolve.

Amy wrapped a length a white rope around one of each of their hands and held her own over theirs. "I've had to create a spell for this because the closest I could find was a handfasting ceremony, a magical version of marriage and that's not what we're looking to do here."

'Magic forces far and wide

Heed to my call

A mother's love for her child

Shall be her child's shield against the dark

So mote it be

So mote it be

So mote it be!'

The white rope glowed a bright, blinding light before returning to normal.

"Okay, so something happened." Faith said. "But was it what we wanted?"

"I'll do another diagnostic and check." Amy told her and combined the diagnosis ingredients in a bowl and set it on the floor between Buffy and Joyce and once again ignited it.

"Wow." Amy said. "I'll say. No more demonic energy and I can see the connection between them, it worked."

"Well, lets go make me a Wesen and then we boot Mr. Windy Price Tag out of town." Buffy grinned. "He's not going to have any reason to hang around if there's no Slayer in Sunnydale!"

Xander had already spoken to his Uncle Rory who'd agreed to let them have the unicorn horn so they piled into their cars and headed over to his house to complete their plan to help Buffy.

"Come on back to where I keep my supplies." Rory told them. "You're sure you want to do this, Buffy? It means sacrificing your one chance at a normal life. It means answering to the Wesen Council instead of the Watchers Council and the laws created by the Wesen Council and it means that if you go rogue, we Grimms will have to hunt you."

The steely look in his eyes made Buffy stop and think for a moment. She'd been going pretty gung ho here ever since discovering that demonic power in herself, did she really want to be a Wesen? The only Unicorn Wesen in Sunnydale? Would Pike still want to be with her if she did this? Could she find a different purpose? She probably could, but this, hunting vampires and protecting people had dominated her life for three years since she'd turned fifteen and being Wesen meant she could still do that and still have a life, maybe a long life. She'd been something other than normal for so long, she didn't think she could be normal again. It would be like having her arm cut off. Her mind made up, Buffy nodded. "I'm sure."

"So am I." Joyce said. "She's not going to be Wesen without me."

"Mom!" Buffy exclaimed.

"I mean it, Buffy, I promised to protect you and that means all the way. I won't let you be alone in this."

Buffy felt tears in her eyes. Her mom loved her that much, to change herself so her daughter wasn't alone.

"There's just one problem." Rory said. "There's not enough horn left for two spells. Just about half an inch and Amy's going to have to grind the whole amount to have enough for her spell. But if you're determined to share this with her, I do have the tooth of another Wesen analog that you can use. You'd be a different Wesen, but still Wesen."

"And Buffy won't be alone." Joyce nodded. "I'll take it."

"You should know, this particular Wesen and its analog are both extinct. But unicorns and Abath are both close to extinct as well." He handed the horn and a tooth to Amy, who prepared her spells before casting them, creating an Abath and for the first time in centuries, a Jambavan, a Bear Wesen native to India where once it was considered a god.
