Was Tom meant to die in the fire?
In one of the flashbacks towards the end of the episode we see Tom calling his mum Carol (Maureen Beattie).
Just after he kills his family he says to her: “I just wanted you to know I tried my best, I did my best mum, bye.”
His message sounds as if he was speaking to her for the final time.
He then injects himself with the same drug used to kill his family – except he wakes up in hospital after being saved from the house fire.
He looks shocked when he wakes up, suggesting he was intending to die with his wife Kate (Anna Madeley) and children.
