—there is a girl discussing animatedly with four guys—a set of triplets and a very, very tall dude—about the pros and cons of just revealing the existence of other universes to various governments while the five of them are snuggling.

He lets the door close behind himself.

"We might need a chart to organize all possibilities: disclose that Elsewhere and its publicly known worlds exist; disclose that there are secret other worlds attached to Elsewhere; disclose that Milliways exists..."

"We also have factor to whom we are telling what. That second Earth would handle 'there is another type of magic' better than ours, I am certain. The news wouldn't be as shocking."

"And each world we discovered is a branch of its own. There is telling Earth one about Earth two, or the reverse, or telling them about the ocean world and so on."

"I am going to get something to write this up," says the super tall dude, getting up and noticing the new arrival. "Oh, hi? New to Milliways?"

The new arrival's mouth opens and closes a few times, like a fish out of water.

"...you alright?"

"Uh... Do you need to sit down? Milliways is safe."

"Yeah, it's just your average multidimensional hub."

"I—I—I—"

"Let's... get him some water, shall we?"

Felix does that, moving at a speed that no human should be capable of.

"Here," he says smiling, offering the glass to Sadde.

He looks down at the glass. Then at Felix. "No, thank you. I need to tell the five of you something and it is quite overwhelming and surprising."

"—well that isn't ominous or anything."

"Oh? Okay, do you mind sitting with us then?"

"—sure." He zips to the couch and sits, way faster than Felix did.

"Oh, sweet, magical powers! So, what is the overwhelming surprise you wanted to tell us?" Thomas says snuggling up with the also returning Katur.

"I'm not human, I'm a vampire, and when a vampire finds someone they would be mutually romantically compatible with, they fall in eternal unbreakable monogamous magic love with them. It becomes symmetrical when slash if the subject is turned into a vampire. The effect is usually subtle enough that the vampire in question does not notice it. I noticed it, because it happened with all five of you."

"...there seems to be a problem with the 'monogamous' part of that description."

"Yes and my brain is telling me I should have a lot of sex with the five of you right about now."

"That last part hardly sounds unusual."

"More importantly, vampire?"

"And how's that 'mutually' part work, exactly?"

"Used to be human, got turned, now am a ridiculously overengineered species with perfect recall, incredible senses, speed, and strength, don't need to sleep, got prettier, smarter, much more durable, unaging, it is impossible to kill me without tearing me to pieces and setting them all on fire, and if it weren't for my personal witchcraft I would sparkle in sunlight. Disadvantages include the magical soulmate thing, and ridiculous craving for human blood. I use my personal witchcraft to turn off smells most of the time so they won't bother me. The 'mutually' part is just that, if I lay eyes on someone who would definitely work out, romantically, with me, then I am in eternal love with them, and no one else—except, apparently, if there are multiple people for whom this is true and I see them at literally the same time it happens with all of them."
