Well dear, when you make one of the most beloved characters a traitor, then you kill the other one, don't wander why are your readers precocious and suspect everyone in the story! You should be proud actually! 🙂
Situation with Deidre went easier than expected but, then again, I'm sure we haven't seen all of her yet!
She was doing exactly that because she didn't appear to be very clean and tidy woman.
Anyway, it is normal that Toby is missing his mother, so sad that she could so easily get rid of him.
