I agree…Lucius Malfoy and LJG don’t mix well for me (and I actually enjoy Lucius Malfoy). I see young LJG more as Jamie Campbell Bower, who played young Gellert Grindelwald to keep with the HP theme 🙂 I can’t really think of anyone for an older LJG.
I’m in between indifferent and love …I “like” him and enjoy his narrative, but I wouldn’t terribly miss him if he wasn’t part of the series. William, however, I really don’t care for.
