I also wondered about the possible Pennywise connection for exactly the same reasons Falseprohet stated. I worked out what "Elvid" was but surmised he could maybe be another incarnation of Pennywise, we know he is capable of changing his appearance easily. I love Pennywise though so maybe just want to believe it was him.

This story left me feeling frustrated and disgusted.

I started feeling empathy for Streeter and could comprehend him wanting to save himself, and maybe not fully understanding the consequences of his "trade." Yet he enjoyed/took great pleasure in what happened to his friend and his family. Not once did he show remorse for his part in it, and I really wanted to see him get his comeuppance. I disliked his character immensely...oouuu nasty man!
Great job SK.
