Simon’s mom and stepdad have come to stay. They want to take Ben back down to Devon for three weeks in the summer, which causes Simon and Emily to wonder why they are not willing to take Rosie. While Simon and Emily enjoy a rare night out at the pub, at home Rosie successfully has her tea, enjoys a chaos-free bath and goes to bed without an iPad. When Simon and Emily return home they realise that something has gone wrong and some truths are revealed. In the earlier timeline, Simon and Emily take the kids to Grandad John’s for Christmas, but their relationship is at breaking point. As Emily sinks to her lowest point, it’s Grandad John who finally gives her the support she needs.
