Elevator Tone Season 2 Episode 9

Not sure if anyone discussed this yet. But I noticed, on Season 2 Episode 9 when Helly comes out of the elevator and onto the Severance floor it doesn't play the normal C# tone. I tried to compare to when Helena was posing as Helly using the Glasgow Block and it played the B natural tone. The time stamp is 13:13. It plays a B natural... the other time we hear this is when Helly hung herself in the elevator.

Possible supporting evidence . . . Helly goes into Milkshake's office she says "Don't you mean Helly E"... and maybe why Jame comes onto the Severance floor and says "You tricked me"? Though that could be in reference to the OT Contingency thing.

The other tone we hear is B♭ which is a more generic elevator tone
