i love g’raha tia with my whole being, and the conflict about mourning what used to be, and living through what might have been, fits right in with his character, but he was just sort of shoehorned into the last half of DT. if he wanted that kind of depth it should’ve been in EW
if g’raha had been written to be in dawntrail from the beginning, it would have made sense (and if they had made him anything other than Cute Cat Boy loves Food and loves the WOL in endwalker)
that being said, the bit about grief in the boat ride should have been erenville.
When I do a write up for Dawntrail, my biggest story criticism would be scions like g'raha and the twins being thrown in for no real reason when they should've been absent entirely imo. Not every expac needs to have every scion.
