I have so many questions that will not be answered.
What I got from this episode:
There is real Lain, and wired Lain
Whatever Lain does in the wired, it effects the real Lain(?)
i.e. erasing everyone's memory of what evil, knights version of Lain
Lain doxes the Knights leading to their deaths via the men in black or suicide
There is a moment where Eiri and Lain switch roles...so is Lain also god?
Lain's parents were planted to make it seem like she had a family.
Yasuo, her father tells her he loved her(?)
WHAT THE HELL IS HAPPENING?!
