Errol's paternal grandmother Joan is hosting a family lunch and Sam ropes Andy into coming along for moral support. Unfortunately it's just as Errol's 'cool uncle' Rex arrives home on holiday, and Andy embarks on a competition to win Errol's sole affections. Sam and Ben hit a snag in their custody battle, someone's got a crush on Errol, and Andy doesn't know how to deal with Joan after she reminds him of 'that night'. The scene is set for a delightfully tense day at grandmother's house.
