Unless Evan's using some kind of coded signalling, I think he needs some street wisdom lessons.

"Could someone look after this top secret stuff for me for a moment while I do some coding - preferably someone I've never met in my life that claims to be both trustworthy and an expert in flowcharts".

EDIT: Ah, I know what he's up to. It's a deliberate diversion, he's going to leak the false plans then launch the real ones to fool our enemies into attacking the wrong flank. Nice strategy
