It takes a good long moment for Katsuya's brain to properly reboot from hearing 'Shizuka' and 'Ra's attack' in the same sentence. Long enough that he doesn't even quite process Zahra going with 'Catherine' over 'Kaseri'. That's cold. But more than that he sits up- stands, almost, his eyes wide with a terror that comes only with experience as he resists the urge to grab her shoulders.

"Sh...Shizuka," he repeats, his voice trembling. "What th' hell was Shizuka doin' on tha' sta- no..."

No- more importantly, if this was a scenario where Shizuka for what ever reason was filling his role... "...Did my sister fight Malik..."

He looks as if the very thought would make him cry, and not for any foolish reason.

Mere mortals such as they, did not oft survive the wrath of Ra.
