Fernanda recommends these ones and, yes, they do know pancakes, but they would be happy if Scott made them.

Do they know waffles and French toast? He can make pancakes, but it's not often you get to introduce people to totally new concepts of food.

The twins know that French toast exist but never had any, neither did Katur.

Scott makes French toast! 

With foreign fruit! 

It tastes like well-made French toast. 

It's well received by everyone.

"Back to experiments? What else do you want to do with me today?" 

"I want to cast a ritual to understand your imprinting on me better. Then, there are tests for your regeneration and agelessness."

"Okay. Are the others going to want to watch, or will they be okay just hearing the results? I don't know what everyone's schedules are like." 

"I'll be helping, but Katur has work to go to."

"Okay. I'm ready whenever you are."

It doesn't take too long, Scott will have time to take a shower if he decides to. Soon enough Fernanda casts the spell.

So, this spell is meant to poke deep in the imprinting. ...What are the imprinting traits? How does it pick? And what are the limitations of Scott's love for Fernanda?

From the moment a wolf activates, there are potential imprints everywhere. Once a wolf imprints, that pool of many possible matches narrows down to one, and so does the wolf's mind. The wolf cannot imagine a course of action that would hurt his imprint without pain, and cannot commit to hurting his imprint, even at the imprint's request. The imprint is the center of the wolf's worldview. A wolf's imprint must be a woman who is theoretically fertile. There are no other requirements. 

Scott's love for Fernanda matches her potential love for him. If she is capable of loving him in a certain way, he loves her in that way. He would do anything for her, except hurt her.

It doesn't look like something that could be trivially changed (she wasn't going to, because Scott doesn't want that, but it is important to know). And it is absurdly strong.

Is Scott capable of accepting Fernanda loving more than one person? Does the situation improve if Fernanda loves him as well?

Scott can accept her loving more than one person. He doesn't need to be her utmost priority to be happy. 

Everything about his situation is improved if she loves him as well.

Is Scott capable of loving other people? Or even just experience sexual attraction?

(This was meant to explore imprinting limits, so...)

Could Fernanda get Scott to kill someone? To torture someone? To have sex with someone? Is Scott capable of having preferences that are disagreable with Fernanda's (and aren't about imprinting safety)? Generally, is preferable for Fernanda to openly express her desires so Scott can fufill them?

Scott can love other people, but not in the way he loves her (completely, unconditionally). 

He is only attracted to her, now and in the future, and no one else.

Fernanda could get most of those things from Scott with enough convincing, but he does have his own preferences that can contradict her own. 

If she pushes hard enough, she can request anything.

Expressing her desires helps; otherwise, he'll just guess.

All of this is disturbing, but at least it's a defined form of disturbing now.

"Basically: a house elf situation."

"I'm sorry."

"Oh, don't be. With 'house elf situation' I mean that... the best thing to do now is accepting your servitude and treating you right."

"...okay. I don't want you to do things just to make me happy, if they won't make you happy. Because if you're happy, I'll be happy. Does that make sense?" 

"I understand that. I just needed to use this to be sure of what is okay asking from you and how to best treat you in return."

"And what that would be?"

"Keep him around, let him do things for me and not treat him badly." Fernanda says with a shrug. "I won't purposefully develop romantic feelings for him just because, but I can at least have some gratitude and fondness. Scott and I will need to talk more about sex, but that is a thing we could try too."

"Maybe we should try that after other things." 

Felicia quietly facepalms over Fernanda's lack of social graces.
