Not totally on track with Howard. Remember Howard said she was obsessed with death and made it seem like she was determinined to go be with Daniel after HE died. But the differences don't matter it's the final conclusion that absolves HKS and KE of everything that is what counts.
Stern is a suspect. Perper should not be relying on Stern's recitations of what happened as fact. This is what I mean by Perper covering for Stern. The reason why he might be doing so is something else entirely.
