As a Spy, there’s a very tense moment after you’ve ‘sapped’ an enemy Engineer’s sentry, dispenser and teleporters. You retain your perfect disguise, but the Engineer knows there’s a Spy around. It’s not always possible to get far from the scene of the crime before the Engineer comes running, so sometimes you have to rely on a good choice of disguise and some subtle sidling to defer suspicion onto an innocent target.

Dressed as a Scout, I had the best possible chance of getting away with it – Spies rarely disguise as Scouts because they can’t move as fast as a real one, so it looks suspicious if you move around a lot. But I was staying perfectly still, facing the other way, waiting with impressive restraint for the sappers to finish their work, the sentry to kersplode and the crime to be complete.

Sometimes, your character utters a line appropriate to what he’s done. “You’ve got blood on my suit,” if you’ve just revealed yourself and backstabbed someone, for example. Other characters have special lines for if they manage to destroy an Engineer’s structures. The Spy doesn’t have these, of course, because it would of course blow his cover to talk like a Spy amongst enemies.

But Valve may have overlooked, or intentionally ignored, a quirk of the Spy’s deception – he will perfectly mimic his assumed class’s vocal responses. After a pregnant pause as my Sappers fizzled quietly away and the Engineer ran in front of me, glaring wildly for any signs of suspicion, his Sentry finally exploded. And my Spy, in a perfect impression of an asshole Scout, immediately shouted, “I broke your stupid crap, moron!”

Three things happened at once – I slapped my forehead, the Engineer blew me away with a point-blank blast, and the Scout became my favourite personality – narrowly beating the Kenny-esque Pyro.
