Total lack of tradecraft and plot gaps
I know Jack is supposed to be seen as slipping, at the end of his rope, on one last job, and so on, but his lack of tradecraft is inexcusable. He sticks out like a sore thumb in the village. He draws attention to himself in multiple ways. His cover story is laughable. He even continues to wander around the town all alone, at night, even after he knows he's been made by the Swedes.
Speaking of that episode, where he's followed down the steps and has the scooter/car chase ending in the death of the assasin- there's zero blowback for any of that. He is just told to stay put. It's not a big deal in the village at all. A local person on his scooter is shot by an international assassin who is then pursued by an unkown, has his tires shot out and is found dead in his car of a broken neck that has nothing to do with a car crash. Italian police not really interested in international mayhem?
Jack clearly observes Clara speaking with strange men in a car at the cafe. Was this ever explained? He clearly suspects Clara but she manages to convince him of her good intentions at the wood. But do they ever discuss what those men were?
