Get a lock of hair from someone at the ball.
Easy enough. He had just killed his wife and while that stung a lot he also knew how important it was to pay back the debt owed for the Dark Lord. Hitting his finger on the drinking glass in his hand, he surveyed the room around him. Many of the patrons were distracted -- whether it have been dancing or talking with guests each one of them remained carefree. He kept watching till he picked his victim. Downing the drink in his hand he stood up almost cat like and held the drink tightly in his hand. This would be the excuse he'd use. Sorry I was just on the way to get a new drink, didn't see you there. He repeated it over and over again even sometimes practicing the charming smile he'd use. With the target spotted he made a bee line for them, just as he had practiced in his head. Bump into them. Jae bumped into his target, and quickly feigned concern. Ask how they're doing. "Oh no -- I'm sorry I was just on my way to get a new drink, must have been too excited," place a hand on their back. Jae maneuvered his hand plucking a hair swiftly so it would have just been an afterthought in their brain. Swiftly exit the scene in a way that won't draw attention to you. "I promise I won't do that again, I'll drink water from now on. Please do continue enjoying your night," a charming smile, and turn around. Jae headed straight for the bar as to not raise suspicions and ordered a glass of water. Place the strand of hair away for safe keeping. He neatly placed it in a vial he was able to get from the others and awaited further instruction from the Dark Lord.
