You want to hear something funny? I had Tali and Legion in my squad once, and we were doing that N7 mission on the planet with the toxic atmosphere and beacons.
When a Harvester suddenly landed and dropped of some Klixen, Legion said something and I don't know the exact words, but I heard it as:
Threat detected. Y minus or something like that when the Klixon where to my left, but I didn't know that. When I heard Legion say that, I looked down on the ground but nothing was there. And then I thought: "Nice try, Legion, but unfortunately for you, I know how the coordinate system works."
