I can’t see Shin ending up as Abby’s killer because of this. Shin had brought up to Rolf that he had been funding the building of the lab for Rolf for 4 years, which was the duration as to when Stefan was shot down. But remember, the shooting of Stefan took place two years before the casting department hired Remington, much less, the writing team putting it into play of the arrival of the character, so would it work for Li, the character to end up being the killer? When they had Alyshia Ochse & Amanda Setton playing Zoey, Evan’s sister. It came out when Alyshia’s Zoey told Rafe as to who had killed Adrienne. It isn’t a wise move for Sloan to cover for Leo, yes, I get that there is the lawyer/client confidentiality, but, wouldn’t it also be considered conspiracy, given that she plans to keep it quiet & in soap fashion that it comes out in the worst of ways, that it would give Rafe the power to file conspiracy charges on Sloan?
