According to major media reports, the wedding storyline will involve family tensions. Max Branning is said to fall out with his brother Jack Branning before the ceremony. In the flashforward timeline, Penny Branning is reportedly pregnant, and fans speculate that the baby Ethan being cared for by Jack in 2027 is Penny's child.
Some fans have theorized that Max's mystery bride could be Selina Branning, Penny's mother and Jack's ex-wife. Michelle Collins, who plays Cindy Beale, told social media that her character "hasn't got a clue" about marrying Max. This is notable because Max Branning is responsible for the death of Cindy's eldest son Steven, and the two shared a Christmas together without knowing each other's identity.
She hasn't got a clue!
The show has not confirmed who the bride is, why Max and Jack fall out, or the father of Penny's baby.
