Alright.  Fine.  Lazarus' side glance towards him might have had a point; Anton's choice of words were probably not ideal. 

But, it wasn't like Anton had any clue how these sorts of interactions were supposed to go.  He still didn't know who this blond woman was or what kind of legitimate authority was behind those very authoritative words.  Or, the very prominently raised wand.  (Which, Anton had to remind himself was a more impressive gesture than one would assume from a simple, raised stick). 

Then.  In quick succession, two things happened. 

Foxy, as Lazarus had called her, was talking about taking Anton to the Ministry.  The Ministry!  Normally, Anton's stubborn, stereotypically teenager belief that youth made one invincible tempted him to shrug off the formality as unnecessary.  The normal course of action was trumped by the prospect of seeing the Ministry of Magic!

And, Lazarus...

After Foxy fired off a few fireworks, Lazarus turned into a bat!  A bat!  Like, with wings and tiny, pudgy legs and a mouse-like body and really funny cat-ears.  Bat! 

"Holy shit!" Anton exclaimed, excitedly, pointing at the spot where the old, moody fellow had been standing a moment ago.  His gaze flickered back and forth between Foxy and the empty spot, looking for proof she'd seen what he'd seen.  "Did you see that?  Shit!  He turned into a bat!  That was effing, oh em gee awesome!"

This was shaping up to be one of the best and most amazing Christmas Eves ever.  Especially if he sealed his trip to the Ministry with a bow on top. 

"Oh man, Foxy, thank you," he offered, assuming the name the vampire had used did belong to the woman.  "I wasn't sure how much was safe to say in front of him and I, well, I still don't really know who you are."  He rubbed at his neck with a hand, wincing slightly as the bruises protested.  "But, it's lucky you came along.  I wasn't sure anyone had heard my screaming." 

The vampire did not look pleased at the German teen's choice of words.  Tessa eyed him, stony-faced, prepared to summon up more sparks if this encounter went in the wrong direction.  But Lazarus stood down immediately, backing away with his hands up, and then departed by turning into a bat.

Tessa would have let out a short huff of relief, but the German kid was going off again, now gesturing excitedly to the spot where the vampire had been just a moment before.  She stared at him, incredulous.  Did they not have vampires in Germany?  He was acting like he'd never encountered one before!

Thankfully, he seemed to recover his wits quickly, although he also adopted the nickname that Lazarus had employed for her.  Tessa eyed the youth again, trying to decide if it was worth correcting him.  Somehow, being called 'Foxy' was far more distasteful when the person speaking had no way of knowing about her Animagus form.

"You're lucky I did hear something," she informed him briskly.  "There's not many people out tonight."

Now, she had the dilemma of figuring out what to do with him.  Even if the German teen was saying the right things now, a moment ago, he'd been protesting that Lazarus had just been trying to help him.  She didn't really trust him to willingly apparatus himself to the Ministry.

"I'll Apparate us there," she said, stepping closer to reach for his shoulder.  "Stay still and don't move too much, all right?"
