After being released from Aperture, Chell has reintegrated with hyuuman society, but something is wrong. Why is everyone so stupid? Is that green kid really an alien? And did Black Mesa somehow cause the apocalypse? Meanwhile, Red and Purple wreak havoc on the universe, and Miyuki is not impressed. No pairings, mostly canon, post-Portal 2/The Trial.
