Speaking with EW, Katherine McNamara revealed that Mia and William are “siblings in the best way” and that they now “have almost a closer relationship.”
The new reality also offers a glimpse into another one of Mia’s relationships, the one she shares with her big brother William.
That’s great news because Mia’s relationship with William was one of the strongest relationships she had prior to “Crisis on Infinite Earths.”
The siblings didn’t grow up together before “Crisis on Infinite Earths,” but it seems the new reality has altered their history in a major way.
