This seems a bit inconsistent. It’s appropriate that Lottie and Mildred remember how things “used to be” in the original time line, because they were back in 1961 when things changed. Shauna, however, was in the “present day” when time was altered, so just like everyone else in Tackleford she should remember only the “new” time line. Shauna should remember the antique shop as always having been owned by the two old ladies, and if she knew at all who Mr. Beckwith was, she knew him only as a drunken ne’er-do-well. No one on the “present day” side of the time hole should be aware of the previous time line (except probably Grumpaw).
