Lots of people in multiple relationships
Is it just me, or were a significant number of the main characters involved in multiple relationships? Let's see:
* Olivia was married to Mark, but started having an emotional affair with Lloyd.
* Demetri was engaged to Zoey, but slept with Janis to conceive a child.
* Janis was in a brief relationship with a woman after the blackout, but slept with Demetri to conceive a child.
* Nicole was making out with some guy during the blackout, but developed a relationship with Bryce, and possibly later with the guy who saved her.
* Bryce started a relationship with Nicole, but ended up with Keiko.
* Simon banged some random woman on the train, then later banged some other woman.
