Dorothy wanted to speak more but Rory softly patted her hand asking her to calm down. They are in a dire state where they cannot reveal what they are thinking. It would be better if that person thinks that she is a fool who didn't figure out all the clues that were laid out in front of her for a long time.
I'll pretend to be a fool for a couple more days... And in the end, I will make sure you get dragged by the cops, handcuffed and humiliated, just like you made my Liam get dragged!
Rory vowed in her heart.
Rory talked about Ellie, effectively turning Dorothy's attention elsewhere. Derick excused himself and went out. Rory looked at her phone and smirked.
She was pretty sure that her phone was hacked. And who knows? Allison did receive a text from her phone number for the meet-up. Allison might have thought it was from her, but it was from someone else--the killer.
