I didn't see the whole segment, but it looks like she does fess up and Bree gets off the hook...and Gabs too somehow? Self defense I guess? Like she says in that episode to Carlos "I'm a woman and victim and it'll look better for me than you who is a 2 time convicted felon" ...or, something along those lines.
I saw all the ladies hugging in the courtroom, so I'm guessing it gets over with quick.
I did see a preview of Tom standing at the door telling Lynette he was going to file the divorce papers in the morning. But, since EVERYONE is saying the audience will be 'happy' with the last show, I'm guessing they DO get back together.
