I agree, FallonColby, there is something odd about the police liaison officer, now Emily's fiancé.
At first, in the present day bits, I thought that he was trying protect Emily from getting hurt by Toby's belief that he can find Oliver after all this time. However I think answering her phone, lying to her about who has called her and trying to "accidentally" take it away with him when he left the hospice goes beyond this.
I'm not sure why he's doing this, whether he thinks he's protecting her but is going overboard, whether there is something we don't know about the relationship between Emily, Toby and Police Liaison man (can't remember his name) e.g. Toby has previously gone too far and upset Emily, whether PLM is just worried that Emily might go off to France to look for Oliver too and not get married, or whether he has sinister reasons of his own for concealing the fact that Toby has new evidence.
Does anyone else think that Emily is only with PLM because he has a son the same age as Oliver who looks rather like him? I wonder whether Emily appears to be coping better than Toby because she is sort of pretending in her head that James IS Oliver.
Does PLM have a wife either in the 2006 bits or in the present day? He and James always seem to be on their own.
If the house where Oliver's scarf came from and where the drawing was had builders in at the time of Oliver's disappearance, they should be easy to trace. At this stage I guess the trail will lead to Scottish business man, but surely it can't be that straightforward as there are still 6 episodes to go.
I don't understand the bit with hospice guy, I think that I missed that bit. How do we know that Toby beat him up? Does Emily know about it?
What is it that Toby, Emily and Emily's dad did before the disappearance, that Emily's dad thought could be connected to it? I like the dodgy adoption theory but don't quite see how that would work.
I suspect that the program makers are aware of the McCann parallels and that more differences will emerge as the series goes on, for a start, surely there will be some sort of resolution on tv in a way that you often don't get in real life.
