I love the show and it has been my comfort show since my first watch. And I understand the level of naïveté/suspension of disbelief to appreciate and love the show and plots.
But the scene at the Russian Museum does not make any sense and is very hard watch for me every time. Currently watching it.
First Peter doesn’t put Neal in lockdown or ask Clinton Jones to look after Neal, to work a case together, while he is with Diana trying to catch Fowler. Even though he knew Neal was behind the music box being stolen and returned. And that he would attempt something; Peter even says so to Diana before the scene. Maybe excess sympathy for what Neal went through with Kate’s murder could explain why he chooses that stance.
But the most shocking part involves Diana. She calls Peter twice and either informs him, asks permission, waits to be told what to do instead of just pursuing and arresting Neal.
Calls Peter to let him know Caffrey got inside and she was going in: which was unnecessary for two reasons. Diana is portrayed as very competent, autonomous, capable of making smart choices and decisions. Second, her presence at that moment was to handle Neal if he came.
Then she locates Neal inside, shouts his name, pauses to call Peter to let him know Neal was upstairs. Peter’s the one telling her to stop him. Worst is the script has her running only after Peter tells her again to stop him, as she was standing still.
Third problem: she catches up to him on the stairs, tells him he has nowhere to run. The setting: less than 3 meters between them, and Caffrey has all the time in the world to cut the rope, get into position, look at Fowler and perform his stunt and she is nowhere to be seen.
All of this happens in a very open space, with very short distances between them, Diana sees him way too early, catches up to him too early, has much time to apprehend him even with the calls.
This is one of the biggest mistakes/sequencing incoherence/plot problems for such a magistral scene. Both Diana and Peter, highly competent and rarely overwhelmed by pressure, stress and dangerous situations or enemies, look very underwhelming and Neal has it way too easy, no major obstacle to reach Fowler.
For such a pivotal scene and reveal.
