Author note: So it's been a month since I finished posting Part One: Fall. I still haven't finished part three, due to RL stuff, but it's coming along. I do apologise for the sudden influx of OCs in this part, but I needed people for them to interact with. :D
Warning: Sex, pseudo-science, Henry being emotional.
Pair: William Zimmerman and Henry Foss.
Disclaimer: I do not own Sanctuary, because if I did the ending would be more of an ending, rather than just stopping like it did. Stupid cancellations...

PART 2

Reunion

"I'm not sure I like this." Bigfoot mumbled, for the third time in as many minutes. "This is a bad idea." Magnus sighed – her English-bred patience was wearing thin.

"I know, but I've got to try something." She looked back down through her microscope. A newly arrived Abnormal had, in transit, let off a cloud of some sort of toxin. Not twenty minute after they unloaded it, every resident Abnormal had gone haywire.

Henry and Bigfoot had caught one whiff of whatever it was, and Bigfoot had immediately covered his mouth and nose. Henry had frozen in place, until the Big Guy grabbed him by the collar and threw him bodily at Will. The profiler just barely caught his werewolf lover, and then completely overbalanced as Henry buried his face in the junction of Will's neck, breathing in huge lungfuls of his cologne. Will's eyes widened as he was suddenly assaulted by Henry's pheromones.

"What the hell is going on?" he had asked, bewildered. "This is way too early in the year!"

"Almost every female in the place is in heat." Bigfoot had explained. "It's triggering the males as well. We're going to have to fix that, or we'll have a lot of baby Abnormals soon." They had to completely sedate the Nubbins less than three minutes later, as they started attempting reproduction despite the low temperature of their enclosure.

Now, Henry was holed up in his lab, tinkering away with some form of air filter to stop it happening again, and hopefully halt a repeat of the problem in the future. Magnus and Tesla were testing different chemical compounds to try and find something to subdue the effects, Bigfoot having offered to be a test subject.

Their latest effort, the last resort they knew would work, was a blanket gas that smothered the scent of the air-borne hormones. The only drawback was that it would have to cover every air-borne chemical in the Sanctuary to be effective, which would include the ambient gases of the building, and possibly some things they didn't really want to cover up.

"I'm inclined to agree with Biggie here." Nikola chewed thoughtfully on the ball of his thumb. "Helen, I really don't know if masking every scent in the building is a good idea."

"It'll only be temporary." Magnus reassured them.

"Good." Will brought in a stack of papers. "Then can you tell Henry that? He's going spare down in that lab of his." Tesla frowned.

"What's wrong with our dear Heinrich?" Will groaned.

"I don't know; something about residual pheromones." The psychologist shook his head. "I don't get it." Unsurprisingly, it was Nikola who made a soft noise of understanding. "Dude, if you know what the hell is wrong with him, please, tell me." The vampire sighed.

"Sometimes the male of some species emit pheromones regardless of the season. If your furry little boyfriend is worried about that, of all things, we can assume werewolves make use of them as well. He most likely has doubts about why you are with him, and fears this chemical we're introducing will cover them up entirely, and so cause you to leave him." Will shook his head, scowling slightly at the word 'boyfriend' – he and Henry both though the term sounded too childish to apply to grown men.

"He should know that won't happen. I haven't noticed anything even vaguely resembling a pheromone around him in months, not since we got together."

"Doesn't matter." Nikola shrugged. "If he has doubts, he has doubts. Even the most brilliant of people are often brought low by such base troubles." Bigfoot pushed Will towards the door. "Go to him, William, and reassure him." As Will left, Helen frowned.

"That was almost nice of you, Nikola." The vampire grinned, bright and almost cheerful.

"What can I say? Young love, it reminds me of simpler days." Magnus turned back to her microscope.

"I suspect 'love' may be too strong a word for it, but by how much, God only knows."
