Jack turned with narrowed eyes at his new addition to the table, ready to inquire just why exactly he found it necessary to sit with him, when he actually saw who the guy was and made a series of noises along the lines of "OooOOwhoooaaah!" which was conveniently semi-drowned out by Rinoa's singing.
Jack officially didn't like this city.
He squinted at Crowley, leaned in really close, drew back with wide eyes, squinted again, and harrumphed. Last time he saw more of his selves, they were relatively close in looks and dress, but this guy...he just went along with it, thinking he had had another mental break. "Very much so, mate. She is like a Siren, eh?" Yup, just going to keep talking in a low whisper, so as not to draw anymore stares than he was already managing since arriving.
