-Spector- = Himself
SweetestHunni = His girlfriend
AmBam = His Ex
Optimistic = SweetestHunni's sister Haley (though -Spector- and Sweetesthunni don't know that, apparently)
Big-2ce = Possibly Optimistic's friend Tyler, but it's not known for sure yet.

I'll just keep updating this list as more people join. lolz
