No tension— I just have no fundamental interest with a resurrected Shireen.
I’m of the opinion that this is one of the things that the show got wrong and will likely be approached in the books very differently; even if George does ultimately think she need to perish for the narrative. The show created a scene that was out of character for Stannis Baratheon and it has never sat well with me (same with Dorne, Myrcella, and to a lesser extent Essos).
I’ve worked with Didact before (a superhero RP, iirc), if my memory serves so this is not me being unfriendly; I am just offering my counterpoints and disinterest. :F
But if I were to humor the idea that Shireen came back after her (blatantly out of character) father called for her death, then I feel her personality would be reflected in many ways and I’m not sure it would be the same tone and spirit as I initially perceived my concept. She’d be harsher, colder, and find the only faith she has is in the spirits because man has shown her it is not to be trusted at all. She’d return to The Stormlands bitter, cynical, and hollow. While this could be interesting by some degree, the GM has also already decided Edric Storm took charge of her rightful claim so there would still be issue. Unless adjusting that is possible. If so, I don’t understand why adjusting her whole death out of the plot couldn’t be done just to same. Thus it would bring the question of this— what bearing does it have on the setting or the GM characters at that end? Is it really important for her to die?
The only conclusion I can come to objectively is no, but I am not the authority of the RP nor do I presume I am so this is all simply my opinion from what I can deduce.
