Revealing mistake: When Benji imagines putting on a mask of an agent he plans to impersonate, when the camera pans around to first show the mirror, the mirror Benji's hands are further up on his face than the reflection, and the mirror Benji's hands move down his face slightly before the reflection starts to move them. Also, the mole that Ethan has on his left cheek isn't reversed in the mirror image. The "mirror" was actually a hole in the wall between two identical sets (one mirrored), with Simon Pegg and a Tom Cruise double in the foreground, and the mask actor and Tom Cruise in the background "mirror" set.

Question: When Ilsa presents Ethan with his supposed 3 options, she says she's proof the Syndicate exists, but I'm not sure how exactly. She also says the CIA wouldn't believe them right afterwards. They all assume at this point the disc is a ledger though, so why wouldn't that definitively prove the Syndicate is real? I know of course that since it's encrypted they can't open it, but Ilsa doesn't know that! I don't see how she could come to the conclusion that the CIA won't believe them.
Question: Why is it not possible to breach the security at the storage facility and use the robotic arm to swap the cards? It is an option never discussed.
