We're now pretty deep into the first season of 'House of the Dragon' and we've got a good look at the main players involved in the 'Game of Thrones' spinoff.

One unexplained plot-point that is bothering us, and surely a few others, however, is the pretty gnarly wounds that seem to be multiplying over King Viserys' body as the episodes go by.

In this week's fourth episode of the series, we get a good look at Viserys' injuries as he is bathed by his wife Alicent Hightower. We also got an aerial view in another scene when the couple are, well... "coupling" as they like to say on the show.

Speaking as a guest on Entertainment Weekly's 'Game of Thrones' podcast 'West of Westeros', Paddy Considine, who plays the indecisive king, revealed what was really going on.

"He's actually suffering from a form of leprosy. His body is deteriorating, his bones are deteriorating. He is not actually old. He's still a young man in there," he explained.

"He's just, unfortunately, got this thing that's taken over his body. It becomes a metaphor for being king, and the stress and strain that it puts on you, and what it does to you physically, what it does to you mentally."

It all started when Viserys cut his finger on the Iron Throne in episode one which eventually led him to lose a couple of fingers. Since his introduction his illness has gotten progressively worse and it doesn't seem like it's going to end very well.

The affliction is not part of the original books so we have nothing to go on in terms of what's going to happen to the poor fella.

However, if the illness truly represents the metaphor of being king then, with the mounting pressures Viserys is facing in the series, we're sure we'll find out sooner rather than later.

Episodes of 'House of the Dragon' drop on Sky Atlantic and NOW TV on Mondays.
