Sadie smiles behind her mug as she watches Ben and Walter and beams when Walter gives Ben a hug. Look at her two boys bonding, and it's clear to her how much it means to both of them.

She waits for the boys to sort themselves out and finish any conversations about the keyboard before she retrieves the bag with her present in and hands the present bag to Walter. Contained inside is a series of wrapped presents, two small, thin cuboids that rattle when shaken, and two larger, squares, one A4 in size and the other A3.

"Happy birthday Walter!"
