Kyle was about to respond to the conversation, saying that this was supposed to be an observation mission, not an attack on the cult, and that he thought stealth was the best option, when things started to fall apart.  First, the woman, going by Vance apparently, took control of one of the cultist's mind, then made him murder his friend.  Then Aaron started yelling something about terrorists and the CIA (he did realize this was England, not the US, right?), which scared the few patrons left in the place out of there.  That apparently meant that all semblance of stealth was over, as Jackson pulled out his knife and went towards the waitress.  Then a giant man entered, drawing his sword and making demands.

"Have none of you every heard of stealth?" He asked the others aloud.  "First," He looked at Vance, "murder.  Really?  Hope we didn't need to interrogate him, and mind control would come in handy if we needed to do that.  Second," he looked at Aaron, "if you're going to pretend to be a special agent hunting terrorists, don't immediately go back to eating your french fries.  That's a dead give away that you aren't serious."  He looked at Jackson.  "and you, could you be any more creepy?  Bad cop only works if you have a good cop to play it off of."  He facepalmed.  "I'm the youngest one here, but apparently I'm the only one that knows what they're doing."

The waitress took advantage of the ruckus he caused to try and escape.  "Sayori!" she yelled as she ducked whatever reflex attack the man coming for her might make, and a 2 meter tall elf man appeared in front of her, holding a bow.

"I won't let you hurt my child." it said, drawing the weapon and aiming it at the closest enemy.  The Waitress started to run, but Kyle reflexively summoned his tormentor Imp.

"Catch her.  Minimum injury." he said to the two foot tall creature.  Despite its small size it was faster than him and more agile.  Just as he was about to start after her he realized what the elf said.  *The girl is human, not an elf.  He couldn't mean her.* he thought, then realized something. The Fae energy didn't come from her, it came from inside her.

"The Waitress is pregnant with the Elf's child." He told the others.  From his studies he knew that it was possible for spirits to reproduce with humans, the most popular cases being the Nephilim and the ancient demigods, but that it required an extremely strong summon or a tear between dimensions that lets them come through completely.  Because of the efforts of the the Order, however, they were extremely rare in modern times.  "I'll catch her." Kyle said, as he chased after her.
