Nekonata:

Nekonata stands up, a bit appalled at the dragon, "Oh so that's how it's gonna be, huh?" She deftly grabs a medium-sized, glass bottle with a thick, yellow liquid, "Hm, it seems it's my last one. It would be a shame if..."

She tosses the bottle into the street. It shatters, spilling the bright yellow liquid all over the ground. All the while Nekonata is looking at the rude dragon right in the eyes, her bone markings in stark contrast to the rest of her body. The markings are sure to at least make the dragon nervous.

"Oops! Clumsy me. I don't deal with robbers or thieves." She says icily, "Oh, well. Looks like you will have to either go to someone who isn't the best alchemist this city has and buy that, or lick it off the ground. I don't care which."

With all the money coming in from Viper Neko wasn't worried about making new potions. She certainly could lose a few to keeping bad dragons at bay.

(the curse that goes along with the markings is that when people see them they experience a magically induced fear. The severity depends on the dragon. Stronger willed or braver and it might not even affect you, similar to how it didn't bother Karahua.)

Karahua:

(She sounds a bit like Urbosa from LoZ BotW by the way. Here is a video of Urbosa speaking (skip to 1:10))

Kara swivels her head to look at the red dragon beside her, "If you're looking for a blue dragon... I would try down there." She says, looking down at the water again. She didn't know if this dragon knew about her, let alone recognized her and honestly she didn't care. No one ever catches The Serpent.

"Nice to meet you Cataracta," Wave said smiling at her as he did a flip in the water, "Do you like reading? My favorite book is Water Demons, a cool book I read recently (not a book in real life XD)," He said as he held out the book he had brought with him, it was waterproof of course, "Have you met my sister Flare?"

Flare stared at the dragon, wondering how stupid they thought she was, "I was wondering if you knew where he was... nevermind," She sat down, Wave, where are you? she asked again and closed her eyes as she waited for a response. Flare, I'm down with a dragon, I think they like pineapples too, Flare heard Wave say and sighed, "Oh Wave..."

I love reading! She got a little riled up and accidentally splashed Wave when her tail hit the water. Im not sure who Flare is though. She frowned.

Mara walked quietly around Sea Haven's less busy streets. She hummed quietly and smiled just a bit as she went. She had little to do currently. It was somewhat of an idle morning for her. She did wish for some kind of excitement for the day, but had none planned.

Veyrun ducked when Nekonata threw the glass, covering his head. His fur bristled once more. He looked over his shoulder at the shattered bottle, ears flattened. Veyrun looked back up at the merchant, more fascinated then terrified by the runes on her body. He was frozen at that point, just waiting for the answer on the amount due on the large potion he was seeking to buy.

"Flare is my sister, she is great... I could get her right now if you want, by the way, do you like pineapples? Because I told my sister you like pineapples," He said handing Cataracta the book he had, "You can read it if you want, I just finished it."

Nekonata:

"Hmph." She turned away from the potion-demanding dragon, now focusing on the grey one, "Sorry about that. You can have the potion since some customers-" She glared at the other dragon before looking back toward the grey one, "Are more valued than others."

She takes the shiny gold coins from off of the desk in front of the stand, scooping them in a cloth coin pouch around her neck.

"I'm Nekonata, but you can call me Neko. Come back whenever you feel like." Nekonata said, clearly just speaking to the grey dragon. Her bone markings flickered out like a dying candle.

Karahua:

"Mmm, yes. Nevermind indeed." She said, her long, slender fangs unfolding as she yawned. She re-adjusts herself on the building's roof, not longing for the company but not wishing the dragon away.

Yes, I like pineapples. Thank you, Ill try to read it as soon as I can. She was suppressing a giggle. Hes being so nice to someone he just met. Its strange, but at the same time a little funny.

"Hmmm, who are you anyways? I'm Flare," She said watching the mysterious dragon, wondering what was going through their head, "Nice chompers you got there," She said noticing the fangs and taking note of them, just in case, "Are they posioness? I bet Wave would know just by looking."

Wave smiled as he twirled in a circle, "It's nice to have someone to talk to, my sister is nice and all but she isn't interested in things I am. Everyone else I meet just ignores me, it's not my fault I know a lot of stuff," He let out a small sigh.

She smiled. You can talk to me until your sister comes. Im a good listener. She stopped talking and gestured for Wave to speak.
