Good eyes
Quinn had good eyes, and he could easily track things even if they were moving at a fast speed and notice minor differences in people that even they wouldn't perhaps see themselves. Even if Layla was in a crowded place with people walking past and moving about each other, he could have easily spotted her. And now, he did not need to do anything of the sort because he had met the person he was looking for as she exited from the gate.
"Layla!" Quinn called out.
Hearing the name being called out, she turned around. The woman was wearing a curved hat obscuring the top of her head. Her hair was parted from the two sides of the hat, and she had fastened a very particular sword around her waist.
