Today's OneWord: Plants

Say an assassin enters a crowded building. She doesn't use the vent to get to the prime office. She doesn't dress up as some sort of sassy, sexy intern who somehow achieves access to the IT department or the computer database. Instead, she plants herself into the crowd with ease and follows where it goes. Maybe it'll take her up the stairs, or into the elevator. Maybe she'll wind up in the parking garage. Whatever the case, once her target lies in her site, she will be hidden, and as the crowd disperses, she will disappear with them.
