So, basically did Luke let Scratch die or he was just about to help when the omnipotent killer fell and died so easily due to the law of gravity? Such a silly way to die for such an intriguing serial killer, but he has been prolonged too long anyway. A bit sad for Stephen, though he bored me sometimes and the new addition member of team seems give more promises. It is nice to have a fresh start after some dragging episodes! Again, I miss Hotch and his cool ways of delivering lines. Wish he were back then.
