Thru the whole game both never shown any emotions or lately unimportant emotions. The point of this villain was there cold behavior and seeing this treasure hunt as business . It also makes them really boring. They not even kill someone in the hole game (even if they try)! They were given only two real emotional moment. First as Cutter "shots" Scully and Marlowe seen a little shocked. Second Talbots "NOOOO"-Scene. The last one comes out of nowhere and thats what makes it unintentional funny and generates the problem. It just looks out of place and like a last attempt to give the characters some deep in the end. But its to late and makes no sense . If there is an connection, the developers should have shown (not tell) us more sooner. But i like i already said, both never shown emotions and Talbots talks about Marlowe as his client. There is just no deeper connection to note between them.
For shadowing is important or people will not get, miss or laugh about such parts.
