Betryal

So I had a guy step in front of my second Fuel Rod Cannon shot a couple times in a matchmaking, which gave him the option to kick me for the ‘betrayals’. Bugged me a bit, but what are you gonna do. The guy saw my first shot, and tried to sneak in to get the kills, and he kicked me for it.
But what was kinda cool was, when I got kicked, it said the message ‘Et tu, Brutus?’ (or Brute, don’t remember). I don’t know if this is a new message for Halo, but I enjoyed the reference.
