If you thought that Episode 4 of House of the Dragon was a shocker, wait until you see the next one.

Mere hours after the premiere of the latest House of the Dragon episode, HBO dropped a trailer for this coming Sunday's, and it is set up to be quite a bloody affair.

The upcoming episode, which airs on September 18, shows King Viserys talking to his feisty and unruly daughter, Rhaenyra, about a wedding. Over the past few episodes, we've come to learn about how the heir to the throne carries some resentment over his father's longing for a male heir to the throne. It's also why she's quick to shut down any potential suitors for fear that she'll be nothing more than a way to further her father's cause.

But, most recently, a come-of-age Rhaenyra has started to mature. It appears that Episode 5 will see Rhaenyra finally get wed to someone. Unfortunately, since this is a wedding in the world of A Song of Ice and Fire, these events are very rarely joyous.
