I think it happened pretty much as Aiden said it did.......
Yeah...not seeing the holes you're mentioning. I know lots of people who are totally rational when sober, but get drunk and become crazy, paranoid, hateful. Sounds like Meredith to a "T" to me. She thought Aiden was trying to kill her. (He wasn't.) She told Bree same. (Bree believed it.) Maybe Bree planted the anti-freeze, and the tablet. But for now all signs point to Aiden's innocence.
Then again, could be another red herring. (The double whammy.) But it makes the most sense now if Meredith was just a terrifying drunk, paranoid, with a too-close friend who's out to prove the "truth" about someone she (clearly) never liked.
The autopsy didn't show any poison or did I not hear that correctly, just lots of alcohol. So having anti-freeze under the sink, while not wise with a youngster in the house, is not criminal. The antidote for anti-freeze poisoning, at least years ago when I worked for a veterinarian was vodka. Don't know if it still is, but around 50% of our patients suspected of consuming anti-freeze survived.
Or maybe he doesn't like to drink because he watched his wife as an irrational drunk for so many years. I know many people who are like that. They refuse to drink because they are repulsed by the drunken behavior of others and never want to become like that.Just remember, Aiden doesn't drink now. Is it because HE was the irrational one, when inebriated??
