It's wedding day for Roy and Hayley. One would think, because of who is getting married, it will all go smoothly with no hic-ups. Well you would be wrong. Mary, or Physco Mary as I like to call her, has a bee in her bonnet over not being invited to the hen party, so she sets about making it a day they never forget. Just bear in mind that a steam train is involved. Back on the cobbles, Claire is getting an awful time about Aadi's accident and tells the police the truth about Sophie and Sian, who deny her claims.
