Florence could see the weapon pointed towards him but pretended that Max was hidden from his view. It was very difficult to sneak up on Florence as his roots sensed the vibrations of foot steps. In a populated area he probably wouldn't have noticed the movement. But with only a few in the area Florence was paying special attention to each. His root shifted a bit beneath the ground as he kept it ready should he need to spear Max with the vine. He disliked using his main body so overtly. But if need be he kept his vines at the ready. He was in luck as he felt Max step back and returned his attention to Luke for the moment.
