Abaddon had been on top of an old building near the coffee shop when the little scene with some bums and a street cleaner occured. Though there was some violence involved, it wasn't serious enough to warrant his attention or even distract him from what he was doing... interrogating. 

"Please man... y-you gotta let me down! I'll talk I'll talk, just don't move that thing closer to me!"
The pleading voice of a man could be heard faintly from the roof of the building. He was a street thug with some abnormal abilities, involved with a rather troublesome gang. Word was that he had information of the location of the "leaders" of the gang regarding their locations and whatnot, so Abaddon was determined to get it out of him. 
Chuckling Abaddon pulled his extended tendril closer to him and retracted an extra set of fangs back into his body.

"That's the spirit," Abaddon said as he held up the man by his throat. "Now, spill it, or your guts will be the ones that get spilled instead."

The mutant spoke fearfully and hurriedly, detailing everything Abaddon wanted to know. Abaddon flicked out a forked tongue in satisfaction and hissed.

"Good. Funny how someone reported to be so strong and brutal could be reduced to whimpering and bloodied whelp."

The mutant laughed nervously. 
"Ahahaha... so... will you let me down?"

"Yep!"

The mutant sighed in relief, but his relief soon turned to shock as Abaddon laughed. 

"No wait stooooop!"

Abaddon released his grip, allowing him to fall to his death and decorate the ground nicely.

"Ouch," Abaddon mocked as he saw the scene and heard a couple of bypassers scream in shock. He would have remained there to observe, but his interest was soon caught by a different scent. Yes, a literal scent. What once smelled like a human now smelled... differently. Animal like, mutant...

With a growl, Abaddon traveled to the alley where Zed was struggling. He kept himself hidden with camouflage. 
"Odd... he doesn't look like anything but a mummy... I mean human..."
Abaddon memorized his scent, deciding to leave him marked in case of future trouble if he was oit of control like his scent patterns suggested. Afterwards, Abaddon quietly sclaed down the building and headed towards the coffee shop, transforming back into his human self, Scipio.

"Could sure go for a mocha..."
