Thanks for your question! There's no problem with you asking this question, no need to apologize.

I am aware of that situation in Game of Thrones for sure. While usually I would say that characters should stay the same age as canon, and prefer to avoid mixing two different media versions of a canon (since doubles are allowed), I think I could make an exception in this specific case. I know the two stories are just different enough that playing a character from the show is different than the book counterpart, and since your concern is about making things less skeevy, as long as the age is the only thing that would be taken from the show, I'm fine with it.
