You are talking about the three puzzle paintings in Ketheric's tomb, aren't you? I got different dialogue for those "Ketheric Thorm, mourning his daughter. Who knew he had it in him?" and "The mighty general - Ketheric at the head of an army of Shar worshippers." Maybe those are specific to his origin.
I've never played his origin story, so that's new to me. : )
Yes, he was a companion in my playthrough when he said this. More accurately he says:
- "A big painting of a sad elf. Heartbreaking, truly."
- "Now that's what I like to see - an elf at the head of an army. Even a Sharran one."
Here it kind of sounds like he doesn't realize this is Ketheric (and his daughter) he's looking at in the paintings, vs. how he talks about it as origin Astarion.
