Effie crying because she likely followed through and got Lauren up outta here. She might be the only one on that campus who is built for it.
It's the one rule Ghost knew all too well, and still he payed for it, just not with his life. Never personally kill someone's love interest and expect gratitude. He got away with shyt long enough to tell Tommy he never killed anyone he ever loved (Teresi, Holly and Keisha) but that didn't stop Tommy from sensing that Ghost indirectly pulled the strings. Which made Tommy hunt Ghost long enough to actually kill someone he loved.
If you gotta murk someone's love interest, you gotta first let the person know the logic behind it and THEN you go through with it. The person has to be at least 2% on board with the idea, otherwise you're just leaving a loose end. Dead love interest = Revenge, especially if done preemptively, it's simple math.
Oh well, I'm here for the fukkery same as everybody else.
