Tinsel/YMMV

Ensemble Darkhorse: Carol and Tonya.
Manipulative Bastard: The Mensahs are a Brother Sister Team.
Moral Event Horizon: Kwame tricking Soji into giving himself up for murder to save Telema with the assurance that his (Kwame's) evidence will reduce the severity to manslaughter ... only to blackmail Telema into marrying him by using said evidence as a bargaining chip. Even some die-hard Team Kwame fans agreed he had crossed the line there.
Sympathetic Sue: Telema. Angela until she took a level in badass in Season 3.
The Woobie: Angela. Oh, Angela!
