The Aftermath - Part Two: Sliding Gaz - S8.E10

Gaz has fallen into a coma, shortly after telling Donna he wanted to be with her. As she sits by his bedside, she begs God to give him back, saying that she is prepared to take 'whatever the consequences'. She imagines two separate realities, one where Gaz is back to full health and one where he is paralysed. Both possibilities are followed in parallel, which take very differing paths. How will fully-fit Gaz respond to the news that Donna may not want children in the future? Or that he may not have any friends? How will paralysed Gaz cope with being in a wheelchair, with the prospect that he may never walk again? How does this reflect on their relationship and can Donna really take either of these consequences?
