Om någon inte är övertygad av @ zabeus 'utmärkta svar besvarade skaparna av showen Jonathan Nolan och Lisa Joy frågan i en intervju till VultureTV :
In the finale, when Maeve gets onto that train ... [...] Now, it’s just keeping pace with her as she makes the decision. What we understand in the moment is it’s the first real decision she's made all season. Which is, she's not going to fulfill the script she's been given, which is to take this train wherever it's going, and do whatever else she's programmed to do.
Vi lär dig lite mer i den här intervjun, om filmval (spoiler eftersom det kan ge information om andra värdar):
the scenes where hosts are following their narrative are shoot using a Steadicam, whereas the handheld shots show that hosts are acting following their free will.
