This very event struck me as odd. Why would she leave home to take the train to see Matt in the late afternoon while he is at work, only to meet him there and take the train back with him? Was it just to go to a pub they used to frequent? If that were the case, why not make a day out of it on a Saturday or another day when Matt doesn't work?
I suspect there is another reason she made the trip, possibly administrative. Since she formerly worked as a replacement optometrist, she used to drive to different centers. Now, she indicated she may need to take the train to work where Matt works, but would rather drive in case of a stoma problem. As a locum optometrist, she used to drive every day, or at least that's what she said in her earlier videos. It was a given that she would use her car because the train wouldn't be efficient for her. Now, she thought of the possibility of using the train to work where Matt works. That seems to imply she wouldn't be locum anymore, or would be assigned temporarily where he works.
Anyway, the 'Let's take a train to see Matt right before he leaves work to come home.' seemed strange to me, as if she was hiding the real reason.
(Who knows...Maybe Matt grunted a few words about her not remembering much about going to work during their spa vacation, and she then decided to prove him wrong and take the train to see him there.)
Some of the sheep are getting restless about the lack of a marriage proposal. Some had expected him to propose during their vacation. Another asked if she thinks or talks about marriage (with Matt?).
