How did Ahsoka know the specifics of Anakin's fall?

spoilers for TCW, Rebels, and Mandalorian season 2

In Mandalorian season 2, Ahsoka neglects to train Grogu because of his attachment to Din, saying this line:

Ahsoka: I’ve seen what such feelings can do to a fully trained Jedi Knight. To the best of us.

That’s a good line. But when I heard it, my first thought was: how did Ahsoka know this?

Here’s a quick timeline of Ahsoka’s knowledge of Anakin’s fall:

• She interacts with him before leaving to Mandalore in TCW season 7, where Anakin seems happy.
• In Order 66, she survives but believes that Anakin has died with the Order
• Fifteen years later, Ahsoka learns that Vader was once Anakin
• Ahsoka fights Vader and is saved by Ezra
• Ahsoka leaves with Sabine to find Ezra
• At the point we see her in Mandalorian season 2, she is looking for Thrawn and, presumably Ezra.

By season 2, we know that Ahsoka knows the truth about Vader and Anakin. However, in this line to Din, Ahsoka isn’t just saying that Anakin fell. She’s saying why he fell. Specifically, that his feelings caused him to turn to the Dark Side. How does she know this?

At first I assumed that Ahsoka did some guess work in between Rebels and Mandalorian, but she would have needed to realize several different things to come to the conclusion that it was Anakin’s feelings that undid him. These things would be:

1. That Anakin and Padme were married/in love
2. That Padme was pregnant
3. That Palpatine was the Sith lord
4. That Palpatine promised a way to save Padme if Anakin joined the Dark Side

Let’s look over all of those:

1. Ahsoka didn’t seem to know about Anakin and Padme

Ahsoka has very minimal interactions with Padme in TCW, and none in season 7. But while Obi-Wan hints at knowing about the two of them, nothing in Anakin’s interactions with Ahsoka, especially in season 7, seem to hint at her knowing about them.

2. Ahsoka didn’t know that Padme was pregnant

At the point of season 7, Padme is pregnant. If Ahsoka knew this, she would probably bring it up to Anakin, but it doesn’t get acknowledged. It’s also a fairly safe bet that Ahsoka never knew about Luke or Leia – she likely would’ve searched for them if she did, or done what Obi-Wan did and watch them from a distance, but from the Ahsoka novel we know she didn’t do that.

3. Ahsoka didn’t know that Palpatine was the Sith lord

In season 7, the Jedi council was still searching for their Sith lord – and it doesn’t even seem as if she knew they were looking for him, or that a Sith lord even existed, as she wasn’t in the Order at this time. Ahsoka’s interactions with Palpatine are also minimal and never hint at her knowing about his being Sidious. Her lack of knowledge of the events of Order 66 add to this.

4. Ahsoka didn’t know that Palpatine promised a way to save Padme if Anakin joined the Dark Side

Honestly, this is a point it seems like even Obi-Wan didn’t exactly know. But it is important, and the crux of Ahsoka’s line in the Mandalorian – that it was Anakin’s feelings that ultimately caused his fall. (Let’s not even get into the details of either of them somehow knowing that Anakin had a dream that Padme would die in childbirth, which was his reasoning for joining the Dark Side in the first place.)

5. Ahsoka, presumably, never interacted with Obi-Wan in this interim

There is a chance that Ahsoka communicated with Obi-Wan as a Force Ghost in the in-between of Rebels and Mandalorian, but this is a bit of a stretch, and even then, if it was Obi-Wan who told Ahsoka all of this, it doesn’t add up with her line "I’ve seen what such feelings can do." Seen, not heard, but when Ahsoka last saw Anakin he didn’t seem like he was on the verge of falling to the Dark Side – she didn’t see his fall, but she fought Vader years later.

So – how did Ahsoka know this very specific detail about Anakin’s fall in Mandalorian? Given what little she knew about the details surrounding his fall, it doesn’t seem likely that she could’ve pieced that all together entirely on her own. And if the answer is as simple as "she heard it from Obi-Wan," that seems to go against her having "seen" what Anakin’s feelings led to.
