The hard part was going to be making sure that the Mudblood picked it up. The device needed to be in her hands with minutes of being activated or she was risking sending someone else instead and Death Eaters would have to figure out a different plan, but by then the Order would be on high alert for an attack. If this is going to easy for her, she would have to do it right the first time.
The Dark Lord had been very clear when he assigned this mission that Potter be distracted and the Mudblood be taken care of. However, he never bothered to tell how she could accomplish this. Pansy knew why he had picked her; She was more careful than Draco. She, also, knew she was under the Order's radar; if she was even on it. The Dark Lord had not given her a time line but she was not going to test his patience. It does not take one long of figure out sooner is better. Her integrity was on the line and she was not about to fail her first solo mission. If she was honest with herself, she knew more than her integrity was on the line. Everyday in the Dark Lord's service was another day that might be her last but there was no getting out now... well at least there was no getting out alive now.
