When Leon firsts encounters Ada, he manages to subdue her by using his knife against her handgun and remarks:
Leon: Bit of advice: try using knives next time. Works better for close encounters.
- Although good advice for the player in general, this is likely a hint for a very late part in the game where you fight Krauser: he shoots you with a TMP from afar, but when he is close to you, starts using his knife and dodging your bullets. The best way to fight him in this close encounter situation is to use the knife.
- Ada eventually applies the advice when a possessed Leon starts choking her; rather than shoot Leon and risk killing him, she sticks him in the leg with a stiletto she'd been packing.
