Katie in doubts about $cientrology
of course the press tend to exagerate things and pick up on anything that sells magazines or newspapers, but there will be a some truth in this, as Katie will obviouly be challenged by fellow actors about all the stuff on the internet that she may have missed out on over the past few years.
As a new member and considerably lower on the 'bridge' than Tom she will be under pressure to get trained and audited to be on a similar level to her husband. When you think that she is also a young Mum maybe just wanting to be with her child that is quite a lot of work, and will only be possible by somebody really wanting that. Its not the type of thing you would do out of 'love' to somebody, as it will mean she woud have to be 'on course' or in 'auditing' for several hours per day.
On top of that her parents and family are probably reading about the Cult on the net etc and warning her too.
I personally think its only a matter if time before they will break up, as Katie become more mature and realizes her husband is a fanatic of this insidious Cult. From my experience as a former member of this Cult I can only say that a relationship with a non-$cientoilpogist is not really possible, as the difference in 'Reality' would be too large.
I do hope they split, and it would be a great chance to get even more people aware of the dangers.
