Daineris Targaryen, which Emilia Clark played, in the final season of the Games of the Thrones, was the point of no return, when the royal harbor burned down, driving his Dragon Drogon. Ultimately, this led to the fact that John Snow (Keith Harington) killed her for the sake of a common good, as it was afraid that her tyranny would destroy Westeros. But if you look at the scenario of the series in the network, it becomes clear that the changes in the Mother of the Dragons have begun for a long time, and in part, they gave rise to envy to Missander.
During the feather in Winterfelle, Missander and the gray worm moved away from Denis noticeably, and she, although she was glad for a girlfriend, he understood that on this holiday all but her. And the desire of the faithful guard to spend time with the beloved made her jealous.
She is alone, and Varis notices it,
- indicated in the script. It is clear that the gray worm gave her a feeling of endless devotion, whom she could not find in John, although he desperately tried to do it. Even when Snow admitted to her in love, calling his queen, Denis replied:
Is it all who I am for you? Your queen?
In the series, he did not answer her, replacing the words with a kiss before leaving, but the remark in the scenario suggests that Daineris "desperately needs unity and cannot remember the time when he would not feel lonely." Also, it says that even John loved her, he did not approve of what she was doing, and passion in his heart was intertwined with fear. And Deni clearly felt this duality.
So the fierce, which in the end was waiting for the heroine, was quite predictable, and her insane acts became a consequence of jealousy, envy and loneliness.
