I’m thinking she wont attend the funeral, citing her pregnancy, Archie, COVID, not feeling well, etc.
That would likely be the last straw for the Queen.
The family probably doesn’t want Halfwit or MeGain at the funeral to pull focus or have some kind of bratty tantrum as they always do. Since the UK still has restrictions on how many people can gather, however many people are allowed to attend a funeral service right now is probably not very high. With all the other family, friends and longtime staff who will attend, the Harkles can easily be left out for COVID restriction reasons.
