Xaviers!

Tosh was a rookie scientist specializing in engineering, so figuring out what Finn had used on Will wasn't something he could do by himself. Luckily there was a brilliant actual scientist on campus. So, delicately carrying a box full of pilfered glassware/evidence, he knocked on the door to Doctor McCoy's lab with a foot.

Doctor McCoy raises a blue, furry brow at what Tosh is carrying in.

"Been to a rummage sale, have we?"

"If by rummage you mean snoop around a villain lair and by sale you mean take stuff, then yes."

"Strange, I didn't expect this sort of equipment to smell... so much like bacon," He tilts his head in confusion, sniffing.

Tosh himself also smelled rather like bacon. "His lair is a... butcher shop smokehouse. I'm amazed my alter ego didn't eat everything."

He grew serious. "More importantly, he kidnapped Will and injected him with a mixture of these ingredients to disable him... or... worse. We're working on finding where he sent Will after that but I need your help figuring out what this crap did to him."

"That explains the curious bouquet of drain cleaner I detect. Judging by the presumed intent, I would venture 'nothing good' is a given."

"Yeah. I'm... really worried. Some of these labels are for things that are only supposed to exist in mythology, but that seems to be going around."

"And this one is a bit of Will," he said, motioning to a bottle whose neck is gummed up with gooey 'clay,' "... or possibly meat byproduct... but it smells right."

"Well then, I suppose we'd best get to work if you've no other leads," he nods and begins clearing space.

"Thanks Doctor McCoy," he nodded with a relieved smile that was more 'fanboy-ish' than he intended. "Just tell me what to do to help," he said as he began unloading the box.

Doctor McCoy gets to work on separating out what he can, running a battery of tests with reagents and ultimately even running them through gas chromatography and mass spectrometry. He's mindful of the limited number of samples, but he can't afford to leave a stone unturned.

The providence of the items appears to be genuine, as much as can be determined -- the X-Men do have more experience with some of these sorts of mythological equivilents than standard science, and a linkup to the Stark Database at the Avengers Mansion provides some more information -- thanks, Thor!

Most of the immediate information gathered from basic tests and whatnot sort of meshed with what Tosh already had learned via his Trusty Science Phone. There were psychotropics, which would presumably make their subject more open to suggestion. There were motor-neuron suppressors, which could cause paralysis. The Moly and Gingold would likely run interference with Will's natural shifting abilities, though they didn't have a substantial enough amount of material to test that on at the moment.

The vials from Setec Astronomy were a little less clear. These chemical formulas were not present in the database, though they did match the labels on the front. Their purpose was vaguer, at the moment.

"...well then, I would say at a minimum our Mister Stanton is six miles high, and in great pain."

"And... at worst?" Tosh asked. He already didn't look forward to telling Sam whatever the answer was.

"At worst, this is a cocktail that is trying every last thing to neutralize Mister Stanton's abilities."

"I honestly can't say what could kill Mister Stanton, but this is absolutely the old college try. I won't know more until I run more tests on the clay residue to see how it affected him."

"How long would it have taken to gather all these rarer ingredients? Because it feels like this guy started planning this before Will even came here."

"I think it's a reasonable assumption that this has been in the works for quite some time."

"This guy has some variety of precognitive ability, but I didn't think it was anywhere near this specific."

"If this fellow is as old as you claim, he wouldn't need to be precognitive."

"How else could he have detailed knowledge of a guy who was pretty recently property of the military? Unless he has a vast network of moles."

"Which an exceptionally long lifespan would give you the opportunity to cultivate."

"Crap. You're right. He'd have to to keep finding his prophesied white whale with so many more people to sort through."

"For that matter, the Headmistress brought to my attention another Will Stanton who was killed recently, over in the States."

He sighed. "Yeah. That was probably his work too. I just... wish I had connected the dots sooner. If I had then maybe... maybe our Will wouldn't be in this mess right now."
