Just before Rita and Norman's wedding Gertrude tells a few of the other guests about Gabe, who is playing the guitar up front. She says he wrote a letter to the only woman he ever loved but the letter got lost in the mail and then she got lost in a hurricane but the POstables found her and reunited them. There are several things wrong with her re-telling. First of all Hattie wasn't the only woman Gabe loved, his first wife and baby daughter died in a fire. And it was after they got separated by the hurricane that Gabe wrote the letter to Hattie that ended up at the DLO which led the POstables to reunite Gabe and Hattie.
Rita has said several times previously that she grew up in Albuquerque and didn't move to Denver until she was an adult. In this movie she said she had dreamed of wearing an Evelyn Rose original since she was a little girl. The news article that Shane read said Evelyn Rose made over 2000 dresses for Denver brides and it seemed pretty clear she was a local seamstress and didn't make dresses for brides outside of Denver. So it doesn't make sense that Rita would have known about Evelyn Rose as a little girl since she lived in Albuquerque.
Annelise was homeless for many years and her mother died so it makes no sense she would still have her wedding dress (that was also her mother's) to send to her daughter.
Bill said he made Sunny's loom as a wedding present. But later Artis said she and Sunny learned to weave together 25 years earlier with the tribe of the sacred Biami south of New Guinea. But based on when Bill and Sunny met and when Rita would have been born they had to have been married longer than 25 years, more like 35-40 years. So it seems odd Bill would make a loom for Sunny as a wedding gift but then she waited many years until she learned how weave. And that would be an odd time to travel so far away without Bill (since Bill didn't know Artis he couldn't have been there with Sunny) and without Rita who would have been a pre-teen or teenager by then. The whole timeline doesn't fit.
