At the first shot of Sara and Ethan talking on the merry-go-round, in the background there is a guy with a yellow package in his hand walking toward a car on the street. In the next shots of the same scene the same guy is again in the same position.
It is not possible for Ethan Matthews to run quickly for an extended period, without even using his crutch, only three days after his thigh was punctured by a table leg and he has only had basic medical care (except a comment was made that the wound was healing extraordinarily quickly).
It makes no sense for the new arrivals not to ask where the villagers got the talismans even after living in the village for several days. At this point, Jim Matthews even writes down several questions about these key items on his big "problem solving" wall diagram and he could simply ask any of the inhabitants. Yet he keeps pondering instead of gathering that key piece of easily available information.
