Kyon: News to me.
What Kyon actually said was "Shiran", short for "shiranai" meaning he doesn't know that, but AFK translated the line as "News to me", americanised alright.
So if Odex uses this line, it's pretty much guaranteed that they're using AFK's subs. Why not 100%? Because you have to look for at least one or two more unique lines to hammer the final nail in the coffin.
