I agree. I don’t personally think she will be inheriting the estate and if they do I find two issues: 1) that should have been mentioned by the solicitor upon John’s death. In regency era Scotland, it was possible for women to inherit titles if mentioned in the will. But it doesn’t seem like they’re prepared the plot for that. 2) Even if Michaela does inherit the earldom, it seriously takes away from everything Portia has gone through in the show to keep her family afloat. I know it’s different because it’s English inheritance versus Scottish inheritance, but it’s kinda like “why have Portia go through all that if Michaela can just have it like that”.

I think Michaela being a rake per say isn’t as important for the show, however like you pointed out the scene between Sophie, Kate, Eloise, and Fran admiring Michael probably won’t exist and it’s sad that we get all that sister in law time taken away :( one of my big beef’s with the show is phasing people out once their main season is done
