Re: Did Data really still have his emotion chip, in INS and NEM?
The "lock and load" line reminds me of TNG: In Theory, when Data used canned phrases from what appeared to be 50's era television ("Honey, I'm home!"), in order to emulate a romantic relationship. "Lock and load" may have been something he filed away after watching a few movies.
