The last time we see Y.T.'s mom in Snow Crash, its to pick her daughter up and take her home. The second to last time, she's being interrogated by the Fed (her employer), because they keep their employees under surveillance and they know Y.T. has been growing suspicious of their activities, and broke her mother's computer.
In this second to last scene, Y.T.'s mom is in a darkened room, strapped in place, injected full of chemicals, being asked questions by a computerized voice.
"What is it you want to know?" she says. "Why don't you just come out and ask me directly? Let's talk about this face to face. Just sit down together in a room like adults and talk about it."
She feels another sharp prick in her arm, feels numbness and coldness spreading all across her body over an interval of a couple seconds as the drug mixes with her bloodstream. It's getting harder to follow the conversation.
"What is your name?" the voice says.
The Feds know Y.T.'s mom is hiding something here and she's in pretty dire straits. But this scene ends, and next time she shows up, everything appears to be fine and she's being reunited with her daughter. It seems entirely inconsistent.
How could Y.T.'s mom have gotten herself out of the mess she was in in the scene above, and been able to arrive and tie everything up in a happy ending?
