I always get distracted by stupid stuff. How does the wheelchair get into the car? I imagine the driver's seat is modified so it can plug in, as we don't see Bab's crawling from the trunk back to the front of the car, but the headrest in the car is totally different than the one on her wheelchair.
Did they just stop talking for 5 minutes while Steph silently helped her into the car? Is there some kind of sci-fi technology where she puts the chair in the trunk, then the seat like moves back to fetch her and slides forward again?
