It was a few days later when Delmare sat pouring over the blueprints once again and compared it to the machinery next to her, it had been a surprise to find Abe's 'breather' on the desk in her room, but helpful.

"Half of this doesn't match the blueprints!" She moaned in aggravation, using a screwdriver to get to the insides. She noticed more and more discrepancies the more she looked.

"This is badly repaired, this isn't wired up properly, and this…what the heck is this?" Using tweezers Delmare carefully pulled a small chunk of something out of the tube that supplied water to the small tank that went round Abe's throat. Cautiously she brought the metal object to her face, under a magnifying glass, and muttered to herself as she examined it.

"It seems to be a miniature slow release capsule, pushing something into the water supply. Definitely not on the blueprints." She put the metal capsule on the table gently and moved to fill up a glass of water from the bathroom. When she returned, she put on some safety goggles and grabbed a plastic pipette. She carefully opened the capsule and poured a little of the water like liquid into the pipette, clamped the open end, and placed it carefully into the water. Slowly the strange liquid began to bubble inside the pipette and she quickly pulled it out and onto the table before it could explode.

Shocked, Delmare took a moment to collect her thoughts before anger rose in her. The liquid in the capsule was liquid carbon dioxide. It was a well known, though not agreed upon, way to euthanise a fish. Someone was trying to kill Abraham Sapien.

With her thoughts gathered, she rushed out of her room and down the stairs, startling the occupants. She ignored everyone else and ran to the Professor,

"Who has been 'fixing' Abe's breather until I could get here?" She rushed out. The old man blinked in shock repeatedly,

"Hey! Don't talk to my father like that!" Delmare spun around and took in the giant red man with filed down horns and a long red tail flicking behind him and stared up into his eyes as she spat,

"You better sit down and shut up, this is important!" In shock, the red man did just that so she turned back to the Professor. He looked contemplative and answered,

"Andrew penn. He has the highest engineering degree here before you arrived. What's the matter?"

Delmare sucked in a large breath and pushed her anger down, now that she was calmer she could see that Abe was out of his tank on the sofa, sat next to the red giant of a man.

"Can we speak in private?" She asked, glancing to Abe and back again. The professors face hardened and nodded, ushering her towards his office.

As the two left Hellboy turned to Abe, muttering,

"What was that about?"

Abe shrugged his shoulders,

"How should I know? She's unreadable to me."

HI, I researched some stuff and the experiment is true but not with liquid CO2, but with a flake of dry ice, had to improvise a bit haha. It is true with the CO2 used for euthanasia with fish, sometimes it doesn't work or the fish in question has a reaction and dies painfully, so yeah.
