Before persuading Neo to discover the truth, Bugs reveals a rabbit tattoo on her shoulder. They then enter a portal leading to the interior of a moving train in Tokyo.
Here is the YouTube clip from The Matrix Resurrections (2021):
Neo: Where are we?
Bugs: Tokyo. A moving portal makes it harder to track us. Seq is the best of them.
Seq: Portal's clean. Reading our shadows.
Neo: I don't remember this.
Bugs: We don't have to run to phone booths anymore, either.
What does "either" refer to?
