That mayoral donation....
I have a feeling that Fox craftily editted out the reason why Henrietta included a donation to the sitting mayor's campaign funds. When Marla and Maurice were in their bedroom, Maurice kept trying to interrupt Marla to tell her something, but she wouldn't let him. I think Maurice knows the reason why that campaign contribution was made.
Perhaps he said something to Henrietta about how much good the mayor has done for their community (or something to that effect) and that he (meaning Maurice) hoped he would win the next election.
I can't see Henrietta just up and giving the mayor a campaign donation, out-of-the-blue, like that, unless something had been said to her to have her believe that it was something the family would want. It was too strange a thing to do, without some sort of prompting.
And of course, it would make for great tv, for Fox to edit the part out where she's given that suggestion.
If you watch it again, listen to how hard Maurice tries to interrupt Marla at the part right after she has her meltdown about the mayor and you'll see what I mean.
