The huge Game of Thrones callback you might have missed in House of the Dragon

Game of Thrones spin-off series House of the Dragon featured an homage to a major Daenerys twist. 

While Episode one of the prequel featured several references to the HBO series that was on from 2011 until 2019 

There was one particular line of dialogue that may be missed by the less attentive viewer. 

The conversation was revealed in a scene that featured Viserys, the King Viserys (Paddy Considine),

the Queen who is pregnant Gemma (Sian Brooke) and they engage in an exchange of words as the latter is bathing.

She informs her husband: "After this miserable pregnancy, I wouldn't be surprised if I hatch an actual dragon."

It could be an ode to the episode one scene that was featured in Game of Thrones

that was when Dany gave birth to her child together with Khal Drogo. 

Following the birth, she was informed that the child was dead, was covered in dragon-like scales, and had small wings.
