This is random, but I’m rewatching this episode right now and it sounds to me like she was about to say “and [etc.]” but trailed off. It sounded like an awkward isolated comment at the time I was making this graphic, but now I’m sure she meant to say more than just that (like a longer apology or acknowledgement that she understood why he was upset).
Edit: To get even more analytical, it also sounds a bit to me like she’s half saying it to herself or thinking out loud? Like, maybe she was trying to explain that she knew how he felt, but then she felt like it was coming out wrong and that’s why she trailed off.
No one said that it’s an error (at least neither I nor the person who pointed it out did); just a pretty significant change.
