The one thing that baffles me with this whole situation - and I suppose  gives me hope that there is more to come - is that if [Philip] Morris is anything  other than a totally straight up guy, then why did he hand over his  entire haul for the 50th [Anniversary]?
All the views that he is a hoaxer,  limelight lover or con man don't seem to fit these actions. If any of  these views were true, then surely all he needed to do was hand over a  few of the 9 episodes or 1 of the stories at most, while keeping the  rest for a further reveal at a later date. The choice of stories is  quite interesting too, with [The Web of Fear] probably being top of fans most wanted  list and [The Enemy of the World] turning out to be one of the most underrated gems ever.  Quite a lucky find, then, if this is all he got from 10 years of  searching? If another story was returned today, would we all still think  he didn't have anymore?
If on the other hand he is a genuine guy, with the fans best interests at heart, and handed over everything he  had, then all of his teases that have come since should perhaps be looked  on in a more favourable light. If all he could find was these 9  episodes, then by now you would think he would have come clean and be  making a tidy income from the convention circuit.
I think there must  be something stopping  all parties speaking openly about the missing  episodes, and the only thing that would realistically fit this blanket  silence is that some sort of negotiations are ongoing [to return more episodes]. Morris comes  across to me as someone who is frustrated that he can't say more about  the situation and has his hands tied. Why would this be if he isn't  under some sort of non -disclosure agreement? The whole NDA situation  around the last recoveries seemed very strange. Would there be that much  security around nine 1960s episodes being released in a few months time if  that is all that was involved? 
Something that never gets mentioned is  who the "higher powers" that would deal with this at the BBC actually  are. I'm assuming there isn't a 'Department For Covering Up The Existence  Of Missing Who Episodes' at the BBC, so there must be someone in [a] regular  job role who deals with this?
If what has been announced is the total sum of the search, then so be  it, but the secrecy and unusual behaviour still being shown by all  parties makes me think the story isn't quite finished.
