Unexpectedly, the hit leaves Jordan in a coma and fighting for his life, while Simon played the hero – weaving a fictional cover story in which he saved the young man's life after somebody else had attacked him.
However, the typically quiet and grumpy Harry witnessed the whole thing and, in the clip below, reveals to Simon that he holds the information that could change his life forever.
Watch the preview clip now:
The clip begins with a frantic Simon attempting to take a pill, but his hands are so shaky that he drops his glass and it smashes on the kitchen floor.
As he disposes with the sharp remains, he offers to help Harry with his shopping bags – an offer the older man bluntly declines.
As Simon protests, his neighbour grimly informs him: "I saw you... I saw what you did, you and that lad, right there."
The interaction leaves Simon visibly terrified as it dawns on him that he could be facing a lengthy prison sentence for letting his temper get the better of him in one fateful moment.
