"Balcony it is.Tell me about your rich history, sounds fun."

Fenris will do exactly that if a history lesson is what he wants. Fenris has recently investigated the topic because the histories between the two universes don't diverge a lot even despite all the magic. He'll remain doing so while naked and will remain amused by Stiles' blushing.

And here is Felix with a tray of snacks and juice. He raises an eyebrow when he notices the scene.

This does not make Stiles blush less, though he does look intolerably smug about it.

He asks many questions about every other sentence.

This smugness might or might not be the reason why Felix leaves (the tray did have two cups and is unlikely he knew about Stiles).

"You're adorable when you ask all these questions."

"Adorable? Puppies are adorable. Kittens are adorable. Snails are adorable. I am not adorable." 

"Really? Then what are you?"

"Interesting? Oozing with charm? Moderately attractive?" 

"Haven't met you well enough to have an opinion on how interesting you're, but I would say you can be enganging in a charming way. And I do find the parts that I can see to be attractive. And none of that is mutually exclusive with adorable."

"Okay, we can find a middle ground. Is Scott adorable, charming, attractive..."

"Let me think," Fenris says thoughtfully, he floats closer to Stiles, "not sure about charming, my interactions with Scott didn't really reveal his charm, but maybe that is just the situation. Yes to the other two traits. But why are we talking about Scott?"

"Me and Scott are kind of a package deal."

"In the sense that you two are close friends or something else?"

"Uh. We're friends, anyone who likes me has to deal with him."

"Ah, I was confused because you asked if I think Scott is attractive, which isn't relevant to simple friendship. And Scott is perfectly likeable either way. Felix and I have a similar situation, except the prospect of dating the same people appeals to us."

Stiles partakes of the snacks quietly.

"Did I say something wrong?"

"No, I just think we should be professional. And wear clothes, probably. Both of us."

"Well, I can accept a professional relationship if that is what you prefer. I don't think that has anything to do with how much clothes we wear."

Is he blushing again? Yup.

"So. Immortality, we should come up with a strategy."

Fenris snorts. "We probably should. Are you sure you don't want to get more comfortable?"

"Maybe later. We've got plotting!"

Plotting happens. Back home only a few hundred people are aware that this kind of immortality exists, a group comprised of mostly dreamshaping created people, relatives of dreamshapers and the dreamshapers themselves, in descending order of magnitude. The twins held discretion to who would get immortality and sometimes they would trade it for favors. And most people who knew would be disadvantaged if the secret came out or if they antagonized the twins too much. Things have been peaceful enough lately that a couple of times they randomly selected who would get the immortality. Anyone with a public identity would need a new one afterwards since wings are a significant cosmetic change, but are ultimately something known to be possible for humans.

Here, Fenris guesses that they can adopt a similar strategy with the caveat that the immortals would be more noticeable in public so they would inevitably need to hide unless Fenris can add the ability to shift away the wings by doing the magical equivalent of reverse-engineering werewolves. The possibility to make the immortality transmissable like the lycanthrope did cross Fenris' mind but he is skeptical that this is a) possible b) wise until he has a much deeper understanding of werewolves and how they fit in the world.

"Playing with how werewolves work seems like the hardest way to do this, better to use dreamshaping. How does dreamshaping work, anyway, how do you come up with new things?" 

"I would still use dreamshaping. I can 'look' at the immortals and see their magic and how it interacts with the immortality magic and there is some room to improve from there. I'm pretty certain that adding new powers is possible. I just never had the opportunity to dedicate myself to the project."

"And not sure what you mean with 'work', but when we sleep we feel we are in this sort of disembodied and floating in a sea of energy and that energy causes the dimension to expand. Each dimension has it's limitations, Felix can create vast ridiculously luxurious spaces, but no magic objects. I can create the immortality springs, vast frozen wastelands and sea-serpent monsters that guard the former, but basically nothing else. Other dreamshapers back home had similar limits."
