Season seven of Game of Thrones is starting to reveal the culmination of preparation by the Lannister forces and those of Daenerys Targaryen along with her full grown dragons. Her dragons are Drogon, named after Khal Drogo, Rhaegal, named after Rhaegar Targaryen, and Viserion, named after Viserys Targaryen. It should be noted that Khal was named after her late husband of the Dothraki.

In episode four of season seven of "Game of Thrones" called "Spoils Of War" we finally get to see Daenerys riding her dragon Drogon into war while aiding the Dorthraki in an attack on the Lannister’s forces and supply caravans.

The dragon torched lines of soldiers and the supply caravan in this epic fight. The viewers loved getting to see him actually use his fire in this way.

How does episode 3 "Queen’s Justice" come in to play?

We remember from episode three that Cersi’s hand Qyburn shows Cersi ballistas that were used in repel dragons previously from King’s Landing. In episode three we also witness Cersi poison Tyene to pay vengeance to Ellaria in retribution for the murder of Cersi’s daughter. Qyburn had prepared the poison, and HBO’s website explains that Qyburn is, “Trained in the medical arts although not a maester.”

How does it all tie together – could this be the end of Drogon?

Now that we know the history of Qyburn with his knowledge of poisons, or the “medical arts”, along with his involvement in the development of the ballista weapons “Scorpion”, what does this mean for Drogon?

As we saw in "Spoils of War" Drogon took a ballista shot from Scorpion, but it did not seem to have much effect before Drogon roasted the weapon the ash. However, it is conceivable that Qyburn has applied his knowledge of the dragons and his skills with potions to put poison on the spear. With all the twists and turns in "Game of Thrones," we know that no one is safe, and nothing is off the table.

Will we see Drogon be slain in the end by Qyburn’s poison?

Finally, with Daenerys now knowing that Cersi has these weapons, how will that affect future battles? With Jamie being knocked into the lake, will he be captured by Daenerys and the Dothraki? Will Jamie being held prisoner, would that be enough to force Cersi to give up King’s Landing or would she see him sacrificed first? Sound off with your comments and thoughts below!
