There was a slight thump coming from above, and as one's attention might be drawn to the ventilation grill, leather-wrapped fingers slid carefully between them before applying enough pressure to get it to swing outward. The hands drew back within the duct, and after a moment or two a head popped out to look around.

A hooded head with a metal face. With glowing blue optics. At first he was turned away from the clone trooper and the doorway, but that corrected itself soon enough as the head tilted up. Those blue eyes widened briefly, and then the hooded figure pulled himself back in with a muttered curse of some sort.
