Caterina Maybe Not So Innocent

I saw a clip online this week that speculated that Caterina, the mom, maybe isn’t Clyde’s victim. Maybe she’s working with him or he’s working for her. A few thoughts: did she order Abigail’s killing? Is so why? Interesting that she shoots Clyde right when he was going to provide Chad more info about Abigail. She was also a good shot, hit Clyde to kill him, not injure him. She seems to be comfortable handling a gun. What is the John connection? Has she really been held by Clyde all these years? Also, who is the children’s father, does he play into this?
After I saw the clip I started seeing holes in the Caterina story.
