When they were at the Etheric Prison, Jackal set his backpack down. He began to root through it, and then pulled out a small object. It looked like some sort of electrical device to Justin, which was further supported when Jackal pushed a button on it, and a tiny antenna extended out from it.

He looked at it a bit, then sucked his lower lip. "Hmm, looks like we have some interference. Not terribly surprising, in fact, finding the source of it might help us track down the Ether Bunny. Can someone re-calibrate the Astral Grounding Rods and someone modulate the frequency while I check some measurements?"

"Oh great, not more technobabble," Alex said, rolling her eyes. Mike handed her and Harper some long thin cylinders she hadn't seen him acquire.

"Just stick these in the ground and try to get them equidistant from one another," Mike said. "Well, you know for whatever definition of 'ground' and 'distance' you have in the Astral Plane."

"Justin, do you have a magi-multimeter?" Jackal asked.

"Oh yeah, it's one of my wand functions," he said, pulling out his wand. He tapped it a bit.

"All right, could you measure the resistance between here and here?" Jackal said. He had opened the box, and he pointed to two test points.

Justin did as he was told. "Looks like it reads 150 gnohms," he replied.

"Sounds normal," Jackal said. "How about the potential?"

"Fifteen ghoults," Justin rattled off.

"So that's point one milli-imps. Still seems all right."

"What the fuck are you talking about?" Alex asked.

"Electromagical measurements," Justin explained.

"Yes, but do they mean anything?"

"Why didn't you pay attention to dad's metaphysics lectures?"

"A better question - why did you?"

"It's coming in handy now," Justin said smugly.

"Dammit, you're right."

"You two are modulating the frequency, then?" Jackal directed to Mike and Harold. They nodded. Jackal went back to looking at the readings with Justin.

"There," Jackal would say to Justin, while Justin would measure the points. After a bit of this, Jackal called out to Mike and Harold.

"Hey Mike, Harold, come over here," he said. They came over and took a look at the readings as well.

"Does that signature look familiar?" Jackal asked. Mike and Harold nodded.

"Yeah," Mike said. "Looks like the Ether Bunny all right. Good job."

"Well done everyone," Jackal said.

"Um, what'd we just do?" Alex asked. Harper also looked confused.

"We detected his psychic signature in this psychic interference," Jackal explained. It was still lost on Alex.

"Basically we should be able to track him down," Justin explained.

Alex nodded. "All right, good enough."

"This way," Jackal said, shrugging his pack back on and setting out in a once-again seemingly random direction.

They traveled through the featureless void for what felt like a surprisingly long amount of time to Justin and Alex. Once in a while they would stop and repeat the measurements they took earlier, and Jackal would adjust his path by some arcane reasoning that the humans, both mortal and Wizard, couldn't understand.

Then, through some equally esoteric knowledge, Jackal suddenly stopped.

"Worse than I thought," he said, rubbing his bearded chin. "I think he's manifested on the material realm."

"That's not really a huge problem," Mike said. "I mean, not unless his psychic potential is over, say, nine kiloghoults. And even that's not a problem unless his resistance is lower than about 66.9 millignohms."

"Can't tell, really," Jackal said. "Not without getting closer."

Justin drew his wand, and Alex decided that it would be a good idea to do the same. Mike checked his gun. Harper just looked nervous.

"All right, let's go," Jackal said. "On three. One. Two." On two, Justin and Alex began preparing the spell to shunt them back to the material plane, while the three celestials began to tune down their frequency.

"Three!" Jackal cried. Alex and Justin let loose their spells, letting it envelop Harper as well.

There was a blindingly bright white light. When Harper could see again, she was in the middle of Times Square.

"Well, that was interesting," Harper began to say. Unfortunately she couldn't get much more out, due to the giant, slightly anthropomorphic and yet incredibly feral looking bunny rabbit that was currently marching through the city.

"So, what's its psychic potential?" Mike said wryly. Jackal looked at his device.

"Looks like it's about... 8K."

Mike closed his eyes. "Please, for the love of God, and I do mean that literally - is his resistance..." he paused and did some calculations. "Under 52.89 millignohms?"

Jackal looked at the device, then looked hopelessly back at Mike.

"It is exactly 52 millignohms."

"Fuck! Fucking shit hell damn fuck shit motherfucker," Mike cried. Such an outburst of expletives from him had never been seen before by any of the gathered company. They all looked at one another. This could mean one thing, and one thing only.

They were royally screwed.

A.N.: There are a handful of you who got the the first joke about the psychic potential. I know you're there, don't hide. I hope you chuckled. However, there are a select few, even out of that handful, who realized that there was another, even more obscure joke hidden in there. Most likely, they are contained within the set of those who got the first joke, but only because I can't imagine anyone in the set of all people who would get the second joke but not the first would also be in the set of Jalex fans.

My hint, if you want to get the second joke - do the math on a relation that relates resistance and potential. Second hint - it's not current.
