Westworld: Questions

Clementine appears to have been the madame when William appeared. She is seen outside with another girl in S1E02 and Maeve is never seen in that timeline.

Dolores escaping sometime is one of the possible variants of her loop. Once we see her get shot, then there is a glitch, the guy who shot her says the same thing again and she realises she has to run away. This is the same loop played twice but the 2nd time she remembers what is going to happen and reacts to it. Then she is shown arriving at William's camp. She's been going through this many times. In S1E05, you'll see her with William and El Lazzo in the train, then you'll see her again alone in the wagon in the same situation. The same will occur at the beginning of the episode: she is first standing alone in a cemetery before Pariah, then she is there with William talking to her. She is retracing her path alone, trying to make sense of the memories she can access.
