truee, but i have a feeling that mielle was the one who suggests that she push her father off, mielle wants to please isis to marry oliver(is that his name?? i forgot lol). if it was isis, she would probably suggest pushing aria off rather than the duke as there will be no other witnesses other than mielle and aria. if mielle starts confessing she will admit she was working with isis and that will put isis in a tight spot so I think mielle came up with that plan.
x x lil spoiler x x
mielle will be found guilty after the third trial with aria as she starts being hysterical, blaming aria for pushing her father, and seeing asher appear out of nowhere, and then disappearing with aria. the judge and a lot of people suspected she was under the influence or smth. her father did not die, from the spoilers he was unable to talk and walk I just don't know if that was permanent or temporary.
both of them are so smart omg, aria said to mielle when she asked her when will she came back and aria replied with late at night or smth and everyone heard that so that will throw the suspicion to mielle as nobody saw aria coming back. aria wants the date recorded and such as a proof that she didn't come back at the house at all. for the bracelet, i'm sure mielle will point that out, asher will give another bracelet to aria that looks similar to that.
