SPOILER
moral of the story:
learn from Supernatural, and burn the body of people you killed so they dont come back and fuck up you relationship
What? You mean Sydney? 12 years old + lacking discernment, Chase will basically be acquitted.
The person most qualified to seek revenge is Flynn──the only person who cared about Sydney, but he chose not to do it, even though he had the ability to return to the scene of the crime.
Should Chase be punished? For what? Justice? This is somewhat morally ambiguous. If he were punished, who would be happy? Syd's family doesn't care at all—they didn’t even bother with a simple judicial autopsy, if it really was murder.
