DANGERHey, Medic! Heal me!Crap! I´m about to drop dead!F.Y.I. I'm a spy.
To those who insist on changing it back: F.Y.I. I'm a Spy is usually translated into ""對了,我是Spy" in Chinese. It's an obvious reference.
It is also semi-official as the same translation is found in the Chinese language script pack for TF2 (tf_tchinese.txt) for the achievement "F.Y.I. I'm a Spy." Great! Eirin is in our team!
