[On whether there was any truth in the line, “I’ve had lots of time to think about how good I was at seeming good?”] I think she’s articulating out loud something she’s always known about herself.

She’s giving a narrative to Tommen that helps convert him at that moment. Maybe she was able to mix a bit of the truth in there – that’s the most effective kind of lying isn’t it?
