So with Tom, when we know he's the culprit. It transpires that he was lying about ever being in the Army and also the truth about his being NC with his parents.
But were was he all the times he said he was with the Army pals? Did we ever find out? Bigamist or what?
Also if he had so much debt his parents had to bail him out how was he able to afford the house?
I felt like he became a bit of an unrealistic panto villain and was a bit Aye, OK then about the whole thing like Anna's dramatic attitude shift to Rachel as well.
