In Video Games, Adventure Games in particular, characters often talk to themselves. Not only is this pretty odd in itself, but also they tend to do so in a way that people simply do not in real life. None of the other characters find anything odd about their friend wandering around saying "It's a shiny key." "That doesn't seem to work." or "Hmm, this door appears to be locked." This can become one of the Acceptable Breaks From Reality on occasions where the dialogue is in the character's head, but when spoken aloud, this can be on the verge of He Knows About Timed Hits.
