[YOUR a expandable]

You walk into Sebastians shop to see him sitting weekly working at his little desk on making gadgets like trip wired bombs for the doors. While his two main arms worked on it his third arm clutched his lower abdomen, his long tail replacing legs was draped around him and across the floor, his whale like tail fin rests on his desk. His esca lights up the small light space infront of him, he groans softly at the ache in his stomach before he turns and notices your there.

You quickly ask him whats the matter, but he sighs, and moves his long black hair out of his third eye. When he moves his scarf lifts slightly showing his glowing blue neck gills, he was on his period but surely he wasnt going to tell you that. He replies with a normal snarky growl.

Sebastian: "its just some stomach pains, are you always this nosey or is it just with my business? Im trying to work so fuck off and get your supplies"

He turns back to try to work although his hands shake slightly, he wasnt feeling well.
