I think Francis looks like a weasel.
A thin boy probably with a thin boys todger, lucky enough to marry a virgin with no context to diagnose his obvious thin deficiencies... Although Lola would know the difference between a boy and a man? (the actor is 23, but I suppose the casting agent who embraced him was looking for a man so undernourished that he could pass for 14 year old boy.).
Although the characters are an appropriate age for each other, even though neither should be psychosocially ready for a physical relationship with anyone (Except that they are royal who have been told that they have to make babies with whosoever they are told to make babies to maintain the line of succession since they could first talk. Brainwashing. Yay?), even though Mary said near the beginning that it is her ladies in waiting's job to tire out all the men in court physically so that she can remain pristine and unaccosted.
All that being said, I have been head over heels in love with Anne of Green Gables since the 80s when she was Anne of Green Gable, so I don't want any bugger to remove Catherine from the board, even if it means that Mary doesn't get to play with a full sized man... Once she is full sized herself? (Adelaide is 24. Seriously!? They're all fully grown adults playing children who are half grown, which mean that the characters are likely to all double in size before they are half way through their 20s.)
Although a real man should be measured in "responsibility" not kilograms, so never mind my hatespeech against persons detrimentally more attractive than I am.
