Fortress Mountain

Or, just maybe, Day coulda read the reports while he was studying the sample of Clarissa Prometheus sent him. They're still a hivemind y'know.

Not that I'm saying Icarus doesn't read reports for fun. He might. He's crazy that way. On the other hand, he might not, being a man with little time to talk and even less to say. Fr'instance, his response to Clarissa; An extremely concise and to the point argument, consisting entirely of a lightning-quick snap kick aimed at her jaw.

And I do mean 'lightning-quick' in as close to the literal sense as it can get without tearing his leg off. While Icarus isn't as strong as Prometheus was, what he lacks for in strength is more than made up for with speed and finesse. He fights with an almost robotically perfect form, every last inefficiency shaved away over hours, days, weeks, even months of training.

Oh, and did I mention he's wearing steel-toe shoes?
