According to Word of God Trina And Corey were adopted with no mention of a mother, In "War and Peaceville" Mina tells Trina regarding Corey "Arent you guys related?" Trina simply responds by saying Yuck. Does she truely know shes adopted or is she unaware? Might count as Fridge Brilliance
And of course theres the debate on whether Trina really deserves being a tool for the band for lyrics. On one side people believe the band are purposely ruining the life of an overly emotional teenager and its no wonder she acts the way she does.Most people however believe she is bad person and deserves what she gets.
