Wow... what a brilliant first episode. First of all, I'm gutted about Baptiste's brain tumour, which suggests he's going to die in this series, so we won't be seeing him in a potential Series 3.
My observations on the plot:
• Why did Daniel Reed (the man who Baptiste now wants to speak to in Iraq) look so surprised at finding blood on the floor (he dropped his shopping when he saw the blood, so he couldn't have known it was going to be there)?
• Who was the blonde woman at Daniel Reed's father's funeral who was making Daniel so edgy?
• What's the significance of the theme park rollercoaster photos that Gemma was viewing on her laptop (at Baptiste's request)?
• Engel, the Polizei chief commander, appears very dodgy and I'm sure he knows something or has some involvement. Echoes of the mayor of Challons du Bois in Series 1 (who it turned out was involved in the cover-up of Oliver's disappearance and subsequent "death")
• Re. Baptiste being chased through the marketplace with 5 grand in his pocket - it was said earlier on this thread that that sequence was just meaningless padding. I'm not too sure about that - the whole set-up with the travel agency and the owner's brother being out of the office - it all seemed too elaborate to be irrelevant to the overall storyline.
• Baptiste, speaking at the end of the episode (in 2016), only said "I believe" the woman who turned up wasn't Alice. So it clearly wasn't established forensically that she wasn't Alice; 2 years later it's only Baptiste's hunch. I'm guessing she really was Alice (could the tattoo, memories of her brother, her parents recognising her face, etc, REALLY be faked?) and we're seeing Baptiste being driven crazy by his obsession to find the truth, like Oliver's father at the end of Series 1.
