I like to draw up timelines for the shows I watch and check whether they’re consistent. It may come as no surprise that HotD has a few issues, as they’ve changed the ages of characters and compacted events to minimise time jumps. Significant time jumps only occur in Series 1 (the dates are taken from accompanying material or the show itself):
- Episode 1: shows the Grand Council of 101 AC and then jumps to the year 112 AC
- Episode 2: half a year later, but still in the year 112 AC
- Episode 3: three years later, i.e. 115 AC
- Episode 4+5: one year later, i.e. 116 AC
- Episode 6+7: 10 years later, i.e. 126 AC
- From episode 8 onwards: Six years later, i.e. 132 AC
- Unlike the first season, no major time jumps occur in Season 2 and Season 3. Therefore, Season 2 takes place in 132 AC, and Season 3 follows directly.
According to the GoT Wiki, all events in Seasons 2 and 3 are dated to the year 132 AC. However, other Redditors have already spotted a major problem: the intervals between the births of Alicent’s children, which are extremely short, verging on the impossible (And yes, Daeron was already planned for the first series, according to Martin’s blog)
Here are the specific details for the show, as found on the GoT Wiki (they are taken from accompanying material or the show itself):
- The main storyline of Season 1 begins in the year 112 AC with Aemma’s death (Season 1, Episode 1). Viserys marries Alicent no earlier than half a year later. (Season 1, Episode 2)
- "Second of His Name" (Season 1, Episode 3) takes place on Aegon’s second nameday, which is in 115 AC as the War for the Stepstones, which began in 112 AC, is said to have lasted for three years. Therefore, Aegon was born in 113 AC.
- Alicent is heavily pregnant with Helaena in "Second of His Name" (Season 1, Episode 3). Aegon is stated to be 3 years old in "King of the Narrow Sea," (Season 1, Episode 4) in which Helaena is visibly around the age of 1. Therefore, Helaena was born in 115 AC. Furthermore, the name days of Aegon and Helaena follow each other very closely.
- Harwin Strong refers to Jacaerys and Lucerys as younger than Aegon and Aemond in "The Princess and the Queen." (Season 1, Episode 6) Jacaerys was born in 116 AC and Helaena, Aemond's older sister, was born in 115 AC. Therefore, Aemond must be born in either 115 or 116 AC.
- Daeron is stated to be 16 years old in "Smallfolk," (Season 2, Episode 6) which takes place in 132 AC. Therefore, Daeron was born in 116 AC.
[Edit: In the following, I am assuming that all pregnancies were carried to full term.]
You can already see that Alicent must have been pregnant constantly in the years 115 and 116. It is entirely possible that she could have had three children in two years if Aegon’s name day fell right at the start of the year, Helaena was born shortly afterwards, and Alicent became pregnant again straight away. Once she gave birth to Aemon in the last moon of the year 115 or the first of the year 116, she must have become pregnant again straight away and given birth to Daeron in the last moon of that year. That would mean that Season 2 must take place in the last moon of the year 132.
In this calculation, however, Aegon becomes a problem: even if Aemma dies in the first moon of the year 112, Viserys waits half a year before considering remarriage. Even if they marry immediately in the 7th moon and Alicent becomes pregnant straight away, she will not be able to give birth to Aegon until the 5th moon of the year 113, meaning that Helaena, too, will not be born until the 5th moon of the year 115 at the earliest, and all the births are pushed back so that Daeron cannot be born until the year 117, which means that he is actually only 15 in Season 2, or that the show has allowed more time to pass and we are in the middle of the year 133 in Seasons 2 and 3. In fact, the septon says in "Rhaenyra Triumphant" (Season 3, Episode 3) that Aegon’s coronation took place a few months ago, which could still be in the year 132 but could also already be the year 133.
Another possibility is that Viserys got Alicent pregnant before they were married. In that case, she would be about three months pregnant with Aegon when Viserys announced the wedding, which seems plausible; however, I can imagine that a royal wedding requires quite a bit of preparation. Furthermore, Alicent is only 14 and very slender, so a bump might already be visible. In that case, however, it would still be possible that the year is currently 132 AC. Furthermore, a premarital affair between Alicent and Viserys would tie in with one of Mushroom’s stories from the book. Moreover, a premarital pregnancy would also tie in with Rhaenyra’s marriage and Jace’s birth. Rhaenyra marries Laenor in "We Light the Way" (Season 1, Episode 5) and gives birth to Jace in the same year. For this to happen, she must have married within the first two moons and become pregnant straight away (at the same time as Alicent), and that episode and the one before it must take place immediately after Aemond’s birth, as Alicent is not visibly pregnant. Incidentally, this would also mean that Daemon must have married Laena straight away and got her pregnant with Baela (the order is flexible) – except if the two were already having an affair and she became pregnant, and Daemon killed Rhea so that he could marry Laena. Incidentally, Rhaenyra’s claim that she and Laenor had been trying to have children is hypocritical, no matter how you look at it.
Of course, another possibility would be that the showrunners haven’t got a clear idea of the timeline or the characters’ ages. This is further supported by the fact that there are apparently members of the show’s crew who describe Aemond as being 18 years old. If so, he would have been born in the year 114 AC, which would place him between Aegon and Helaena in age; however, Helaena is his older sister.
TLDR: There is a chronological issue regarding the births of Alicent’s children, and here are the four explanations for it:
- Daeron is only 15, and the statement in Season 2 that he is 16 is incorrect (this supports option 4)
- It’s already the year 133 AC, and it’s been that way since Season 2 (maybe)
- Alicent was already pregnant with Aegon before her marriage to Viserys (my favourite)
- The showrunners have messed up the timeline (the most likely option)
If I’ve got my maths wrong, please let me know (in a nice way).
PS: I’ve only touched on how the births complicate the timeline here, and haven’t gone into the difficulties regarding the characters’ storylines at all, as that would be a topic for another post. For example, the show has made Alicent’s fate far worse. In the book, she doesn’t get married until she’s 18 and has her four children by the time she’s 26. In the show, she marries at 14 and has her four children within the next four years. Furthermore, Viserys is younger in the book. The showrunners should be ashamed of themselves.
