In Meg's room when Luke first arrives there's a bench with pillows under her window, then once Brian arrives both are gone.
This is the first episode where the door between the kitchen and living room is gone once again for good. It only lasted in that position for 6 episodes.
Meg is only 17 years old, and is not legally an adult. She should have been sent to a juvenile detention center for her crime, not a full-blown jail/prison.
When Chris opines for the days when Meg was as predictable as stock photos on corporate websites, we see - and the narrator says, "I'm a woman in a lab coat wearing goggles, staring closely at a beaker." Only, the female scientist is studying a test tube, not a breaker.
