I knew as soon as they showed Petra in the car with it raining that she would get in an accident. Having Magda return is really tired, even for a show that makes fun of soap opera tropes. This trope is DONE.
Jane's response to the Unitarian minister should have been "I can see how you might think that, but it's okay, I'm confident of his commitment."
(BTW, about the money -- I grew up in the Methodist Church. Ministers were not paid extra at all for weddings. The bridal couple had to pay some church fees -- for electricity, cleaning, etc. -- and it was customary to give the minister an honorarium (in my sister's case, that was $50) but not required.)
I don't understand why Petra's assistant didn't/couldn't keep some shares for herself as a reward for helping Petra. Owning shares does not mean that she has to help run the hotel -- it's just like owning shares in any corporation. (Here the majority shareholders also run the hotel, but they could instead hire people to do that.)
