Hm. I wouldn't make fun of an AI, for their ways are subtle and difficult to discern. Their reach is far, their fingers deft, and their touch light.
Why even *think* it would be a real AI, eh? Of *course* someone on staff is having fun with this (or someone has convinced a staff-member to let the fun exist, at any rate). This is HALO, after all - Cortana Letters, et al. Welcome aboard, Sierra! Pay no mind to the stodgy old Commander in the corner.
