I had read most of the books years ago but never read Mostly Harmless as I feared the end (I had been told). I finally listened to all of the books including Mostly Harmless in audio-book form and I see a few loose endings.
Firstly Fenchurch - We never actually get to find out what was wrong with her, indeed since she disappeared at the very beginning of Mostly Harmless we never heard from her again. So why was she floating all the time? This was never really answered.
Secondly the fish bowl - In So Long and Thanks for all the Fish, Wonko the sane had alluded to the fact that if they put their ear to their fish bowls they had received, they may hear something they needed to know or find an answer. This however, was never mentioned again.
Thirdly the guide - I assume then that since the guide destructed at the end of the book, the original (proper) guide was also destroyed? Do the Vogons still own it?
Fourthly Zaphod - In one of the earlier books, I forget which, we are told Zaphod and Trillian have kids and are living on a planet somewhere, so why in Mostly Harmless does Trillian say she couldn't have kids with Zaphod as he was a difference species, hence why she had Random?
Since initially Adams had intended this to be the final book, (although he alluded to regretting the ending later and suggested there may be a book 6) there seems to be a lot which went unanswered, so I'm wondering if I just missed the answers, had forgotten a page or two or just completely missed the point.
Any thoughts?
