Honourable forumites.
We knew this some time ago, without noting it.
In EtM, the Oracle tells Niobe that Neo’s mind (aka his digital self) is caught in the Matrix.
Niobe: ”Can we free him?”
Oracle: ”Trinity can, but she will have to fight her way through hell to do it.”
Now, those words are transcripts. People wrote what they heard. The Oracle probably said:
”Trinity can. But she’ll have to fight her way through Hel to do it.”
About the Subway “thing”. “The Observer” from EtM figures in the trailers as well. We met him with Niobe AT a Subway station in EtM. So that we may return to a subway is not so odd.
