As expected, after the 3 or four minute mark, Joseph Franklin, his target, quickly excused himself from the conversation he was having with the other man, and rushed to the loo. Frederick placed down the tray somewhere at the back of the room, and quietly slipped into the first door into the toilets, there was a second one into the men's. He concentrated, remembering the appearance of the man that Joseph was talking to, and placed an illusion of the man upon himself. He looked down at himself, and chuckled slightly, he liked it when things went to plan.
He entered the men's toilets, and his target was standing at a urinal. Joseph peered back at Frederick and stood silent for a moment. Frederick quickly worried that he had done something evidently wrong, but then realised that the Joseph was smiling.
"Peter! I have decided what I'm going to do, I'm gonna get the arms off of that contact I used last year, good guy, trustworthy. Do you think that's a good idea?" Frederick waled silently up to Joseph, also smiling, unfortunately, it would cause too much effort to create noise added to the illusion. He slipped the knife he was carrying out of his sleeve, and his smile grew.
"Peter-" Before Joseph had time to utter another word, he was stabbed in the back of the neck, blood spraying onto the urinal in front of him, but luckily only the small tip had gone through, so there was not too much blood. Frederick dropped the illusion, and quickly placed the towel from his arm around Joseph's neck, preventing any blood from spilling on the floor. He dragged Joseph to a cubicle, climbed on top of the cubicle, locked it, and then jumped to the other side. He waved his hand in front of the motion sensor urinals, and they flushed, taking the blood along with the urine.
"Well that's a bit grim." Frederick grimaced, and washed his hands and the knife in the sink. and placed the knife back up his sleeve, ensuring that it was secure. He excited the toilets, straightening his bow tie as he left. He looked around for the aforementioned 'Peter', and noticed that he was in conversation with another person, so Joseph shouldn't be missed for a while.
"Target has been disposed of, yet I agree we leave quickly, as he's in the cubicle, shouldn't be noticed for a while, but we can't risk it." Frederick witnessed the cat fight break out in front of him, and noticed Tris' wig start to fall off. That would be pretty disastrous, and would probably cause the entirety of the mission to fail. Frederick saw this as an opportunity to get both him and Tris, and possibly some others out of the building.
He walked in to the fight, and pulled Tris away from the woman, which was surprisingly difficult, the other woman was pulling back, but Frederick did his best, he needed some assistance. During him pulling her back, he slyly repositioned her wig back onto her head, and sighed in relief.
"Please lady, step outside." Frederick hoped she would recognise his voice, and then they could both leave, and no-one should suspect anything, but if it was too much for Frederick, their resident muscle, Jack, could always step in to lend a hand.
