I didn't realise that you could mess the order of events.
Just as I was admiring that in spite of the countless times I'd done quests and locations/regions in a less linear fashion, the storyline has always held true, I finish the northern area of Auridon having already completed all of Grahtwood and the Queen starts going on about trouble in Elden Root ("Yes, your majesty, we were just there, your brother turned into a big fatty and then died") and then her brother runs up (in original form) and they have a chat. Only an hour ago, we were starting off in Greenshade and she was complaining that someone had betrayed us and her brother's body was lost. ("No worries your loveliness, he's standing behind you now")...
Shame.
