Milly Alcock, who plays Princess Rhaenyra in 'House of the Dragon', discusses the shocking reveals in episode four.

* Spoiler Warning for episode four of 'House of the Dragon' *

We've all woken up with a bad case of the fear once or twice. But, we can't imagine what it was like for poor old Daemon Targaryen waking up on the streets of King's Landing after the night he had in episode four.

It's fair to say this week's episode gave us some surprises. Especially for those unfamiliar with the books.

In a far more understated episode than last week's crab-fest, the show gave us a greater insight into the mind of Rhaenyra as she endures endless attempts to be married off by her father, King Viserys (Paddy Considine).

During the episode, we see Rhaenyra sneak off into the wild streets of King's Landing with her uncle Daemon (Matt Smith) for a few pints. However, things start to get a bit... weird and the two end up in a brothel surrounded by, well, stuff you'd expect to see in a brothel. The two Targaryens then share a kiss in front of some shocked patrons.

However, according to Alcock it wasn't that awkward to film despite the context. "No, strangely enough. [Matt Smith and I] were just kind of mates. So, it was quite comfortable," she told the New York Post.

"We had an intimacy coordinator, and we worked with her through the rehearsal process and blocked it out months before."

The Australian actor added: "Clare Kilner, our director, made sure that we hadn’t seen any of the brothel stuff until we were shooting. So, that was our first time walking through the brothel, and he’s guiding her through the room with all of these other bodies. So, that was quite shocking. You’re like, 'This is kind of weird and silly.'"

As the series jumps forward in time, Emma D'arcy, playing an older version of Rhaenyra, will soon replace Alcock. However, the 22-year-old has already become a fan favourite, and we're sure won't be forgotten easily.

If you thought things got spicy this week, check out the trailer for episode five. We can't wait.

'House of the Dragon' airs on Sky Atlantic and NOW TV on Monday nights.
