Since Arno managed to see Shay through the walls, this means that Shay managed to catch sight of them, too.

Luckily for Arno, the red Aura surrounding the Assassin has been replaced by a nice minty-blue. One of the few on the Turtle. Everyone else showed up as gold, or just blended into the background. Arno was blue, his companion was a familiar gold.

So, as they head up onto deck, Shay's already out there, but hidden in the shadows.

"There a reason you're paying me a visit unannounced?" Shay calls out. "Or is our relationship such that you feel you can just walk onboard a man's ship."
