The "Stick Around" Achievement/Trophy gets its name from Schwarzenegger's immortal post-mortem one-liner after he's nailed an opponent to the wall with a blade, followed by the quip, "Stick around!" Crysis 3 isn't even the only game to use that one-liner as a name for an Achievement/Trophy.
The "Clever Girl!" Achievement/Trophy gets its name from the scene where Muldoon is hunting the raptors, but comes to realize that the raptors are hunting him and he's just been blind-sided. His last words: "Clever girl."
