Their wedding day is simple, just the two of them with Clare and Rob's old schoolfriend as witnesses.
"I, Adam Robert Reilly, do take thee, Cassandra Maddox..." he reels off.
She's barely aware of reciting her own vows, her eyes are fixed on Rob's and he looks so happy she almost cries. She blinks back joyful tears so they don't ruin her make-up. "You look beautiful," he had whispered when he saw her in her dress.
Finally, they are pronounced husband and wife and given permission to kiss. Charlie gives an exaggerated whoop as they embrace. Clare dabs at her eyes.
Later as they celebrate in the hotel bar, she catches him looking wistful and knows he must be picturing his friends here, Peter as best man, Jamie as Cassie's matron of honour, helping her take her shoes off. "You okay?" she whispers.
He smiles at his wife. "Of course."
