Deadly Friend/Tear Jerker

B.B.'s death at the hands of Elvira. What really adds salt to the wound was after shooting B.B., she gives a smug grin to Paul, Tom and Sam. She hated B.B. the moment she laid eyes on it.
Sam's life in general. Her father abuses her for even looking at another guy. It's implied that he molests her. The only happiness she found was when she's with Paul, B.B. and Tom. To top it off, his abuse goes too far sending her into a coma. Without any remorse the father wants the plug pulled. Even when Paul brings her back to life, she's not her anymore as B.B.'s mind takes over, killing people that pissed them both off in life. And just when it seems she's gotten her mind back, the cops, who are pursuing her for murder, shoot her.
