Good episode if a little sad, do think that Siobhan and Jimmy breaking up is a plot device for Amanda Abbington to be absent for a few episodes while she had the baby. Best moments were when Jimmy was trying to hide from Siobhan in the house and Alex's expression realising Molly was Angry in Year 10 and spitting out the yoghurt.
Wish they give Alex more screen time as he's easily the funniest character.
