Alright, so I tried to sort out the ages for each character (again) because people keep insisting that Aemond and Jace are the same age, which makes absolutely no sense. Yes, the show’s timeline is already a mess, but bear with me while I walk through how I got these numbers.

First, Rhaenyra and Alicent.
According to the script, they’re explicitly stated to be the same age. Rhaenyra also tells Luke that she was 14 when she was named heir.

Jump ahead a few years to Aegon’s second nameday: Viserys says on-screen that Rhaenyra is 17, which means Alicent is also 17 at that point.

Then we get the 10-year time skip. That would place both Rhaenyra and Alicent at 27 years old.

After that, the story jumps ahead six more years before the events at the end of season 1, which would put them at 33. You could argue 34, depending on exactly when birthdays fall, but imma say 33. 

Now Aegon, Helaena, Aemond, and Daeron’s ages make no damn sense, but this is literally the only configuration that actually works. If we go by the supposed 15-year age gap between Rhaenyra and Aegon, then Aegon would be 18, which already falls apart because Helaena is two years younger, meaning she’d be 16, and Aemond would land at around 14/15, with Daeron even younger. It makes zero sense.

So the only ages that hold up under scrutiny, and under actual real-world filming laws, are these:

Aegon: 22
Helaena: 20
Aemond: 18

Aemond has to be 18. He just does. Because that full-frontal nudity in season two would not be legally permitted if the character was a minor, even if the actor is in their 20s. There are strict rules around depicting minors in sexual or nude contexts, and the show simply could not have aired that scene if they were claiming he was Jace’s age.

Now Gwayne straight-up tells Alicent that Daeron is 16. If we go by the books, Daeron and Jace were born the same year, which would make both of them 16. Simple enough.

Luke is 14 when he dies. Rhaenyra talks to him about inheriting Driftmark, she tells him she was the same age when she was named heir.

Joffrey is six. Not only is it a six-year time jump from his birth, but Corlys himself confirms the number on screen. 

Now Baela and Rhaena are not twins in the show, which is honestly some bullshit, but here we are. The casting call sheets literally list them at different ages, an older girl at around 10, and a younger one at 8/9, if I’m remembering right. So the “dragon twins” are actually about a year apart on-screen.

If Baela is 10 at Driftmark (per casting), then six years later she’s 16, which conveniently matches Jace’s age. Rhaena, being a year or two younger, lands at 14/15.

Next is Daemon. The scripts specifically say he’s in his 30s during the Heir’s Tourney. Add the show’s 19-year time span, and depending on exactly where in his 30s he started, he ends up in his 50s, possibly early 60s. Same with Mysaria, who is also scripted as being in her 30s, so she ages into that same 50s/60s range.

Criston Cole is said to be in his 20s in the script. Early 20s? Late 20s? No clue, but given how he’s positioned near Daemon in the books, late 20s makes more sense—meaning he’d now be in his late 40s or early 50s.

Otto and Corlys are both listed as in their 50s at the start, which puts them in their 70s by where we currently are in the show.

Rhaenys was said to be in her 40s early on, so she naturally ends up in her 50s/60s as well at time of death. 

So yeah, that’s what I’ve got. None of it makes any fucking sense, but honestly? Who even cares at this point. The show clearly doesn’t.
