Flashbacks show a reluctant Al telling Sheila of how he annoyed the school bully after he told Al to stay away from new girl Gracie.

We also learn that Sheila had taught Al a lesson by making him smoke a cigarette which he had taken from her and more importantly how she had given him his first Sci-Fi book – War of The Worlds by HG Wells and Al describes sci-fi as ‘A world where the tiniest bacteria can defeat the biggest bullies.‘

This episode will air Friday 5th April on BBC One
