A documentary about Roswell gives Lain some valuable information about the pioneers of the WIRED. Later, at the Cyberia, J.J. tells Lain that she left something the day before and hands her an envelop with the Knight's logo on it. The envelop contains a chip. Believing this was the other 'Lain's' doing again, she decides to call Taro's bluff and go on a 'date'. Taking him to her room, Lain demands that he tell her what he knows. Together, with Taro's information and the mysterious chip, Lain finds out more then she expected.
