hah - another example of ridiculous specious reasoning. the deadly trap was set way before sarah met tom, dick and harry. i assume it was dick she fell into the sack with, but nonetheless....the trap was set when daniel decided he wanted to be a big shot in the org. if he had never done that, if he hadn't had those studies (a pet peeve of mine...how is it that people become 'studies'...they lose their being and become a thing) - but, had daniel never gone out in service and met those dudes, and never studied with them, sarah most likely would never have known them, so she wouldn't have had her fling.
but then, maybe she wasn't all that in love with daniel. maybe it was one of those marriages that kids too young rush into with someone they barely know, just to have legitimate sex - and later realize they were stuck with the entirely wrong person.
