Anything someone said while the Chief was in his armor, she can get without him having to be involved. But that's still less bad for Wash than "I read the comments in the firmware code in your armor."

Though, she's smart enough not to implicate the Chief. She might implicate the anonmeme, actually.

Basically I don't want to fuck up Wash and the Chief's CR, and Cortana is capable of discretion.
