Question about the ending (*SPOLIER ALERT!*) for those who have seen it!
In the last 20 mins or so when Poirot told everyone in the train car how he envisaged the murder, that ends with Bianchi (Martin Balsam) saying that he elected the "first option". Then everyone is pleased that the case is solved also as Poirot has said that there must've been a man in the train guard's uniform. I've seen the Blu-ray twice as I fell asleep the first time & so I replayed it the following night but just don't get the ending! McQueen (Perkins) stood up & took a bit of a bow when Bianchi said he elected the first option too. Please someone help me here!
Thanks.
