"Is that your attempt at comedy?" He blurted suddenly, brow arching in genuine confusion at the other's casual remark about his own death. Frankly, he didn't understand Eui. Granted, he didn't have many reasons to be happy and cheery, but Mordecai didn't really like this blasé, shut-down, blankness. If he continued to act like that at the convention, Mordecai would kill him if need be. He didn't really care if he had to get rid of one of his favourite 'creations'. Hell, he'd killed the only man he'd ever loved, so some miserable little teenager really wasn't an issue.
By the time the next evening rolled around, the convention at the top floor of the apartment was, predictably, of the highest standard. No expense was spared and every table was decorated to perfection, every bottle of wine and champagne worth more than most people earned in a week, and every person in attendance donning designer clothing and dripping in wealth. And in the middle of all this, socialising effortlessly despite being a misanthrope who generally hated people, was Mordecai. He faked smiles and niceties to the millionaires who invested in the research for their own benefits. Of course, Mordecai could fund everything himself... but there were benefits for himself to get close to these people - he could blackmail the hell out of them later in life for the fun of it. It was a long-term plan, but he was immortal. Time was no object.
And, predictably, Eui-Tang was paraded around like a toy, being prodded and looked down upon as though he wasn't a human with feelings... because, in this environment, he really wasn't.
However, he wasn't the only transformed human at the convention. Wandering around beside a 40-something man was another human who had clearly been experimented upon... and apparently, Eui had been lied to, because he wasn't as unique as Mordecai made him out to be. The girl who was wandering about glued to a human's side was similar in that she had the same rabbit-features as Eui did... and once she saw Eui, her bright pink eyes widened because she knew him.
The girl wasn't a stranger to Eui. They had been at school together until the girl, Bianca, disappeared aged 10. There'd been searches for her and news reports played out in the media for the cute blonde-haired schoolgirl... and clearly, given her transformed state, she'd been snatched up like Eui and put to experiments she didn't consent to. Unlike Eui, however, she was just given away to the man at her side, treated like a servant or a maid to him. Mordecai didn't like giving away the creations because of the risk of outsiders finding out... but he made one exception, and that was for the man who bought Bianca.
Somehow gaining confirmation to wander on her own, taking advantage of her owner's distraction, she immediately headed to Eui-Tang, shyly and with a bashful smile on her face. "...Hi. You... I remember you, I... I used to live near you, a-and we played hopscotch and drank milkshakes and... I... they got you too..."
