So now most of us know about the mysterious waitress at Barry and Iris' wedding, who wished a good luck to Barry before his wedding. Now that character didn't seem ordinary for her awkward way of interaction with Barry. Many are speculating him to be Barry and Iris' daughter Dawn Allen from the future and she is more likley to be actually Dawn. Here's why;
Her expression on her face seemed that she was very excited and her face had an emotional sympathy when she held Barry's hand. In the comics, Dawn never get to knew her father for he died in the Crisis event. Probably she was born after Barry died in the 2024 event.
Appearance on Supergirl
Secondly she appeared first on Supergirl and we sort of have the LSH on the show and Dawn was a member of the LSH.
What do you think?
