While i absolutely appreciate the conversation around canon and the Forgotten Realms i am specifically referring to the fact that BG 3 is canonically set in the BG1-2 world and timeline. It is not a spiritual successor it is a direct successor, they took great pains to call this out and i think from what we have seen to date they have honored their word on this mostly and have done a good job. Like i said they should explain the delta, they do a good job of tiebacks and explanations of things between bg 1 and bg 2, but to me this is a potential miss, of course we haven't met Jaheira yet so she may speak to it but i hope they account for the potential discrepancy in some way.
I bet you $100 they won’t account for it at all. It’s just an epilogue card. Minsc’s has already been officially retconned, so disregarding Jaheria’s is pretty much a given.
