Wait, I forgot/forget too. Who did they kill? Crystal's ex that they blamed for her miscarriage? I vaguely remember Blake beating someone up, but that's it.
I think technically you can go to jail if you assault someone, and they later die as a side effect of the assault. Even if it wasn't the direct cause. Or if someone dies while you are committing a crime, you can be charged with felony murder (at least that is what they said on How To Get Away With Murder).
However, whether that can be proven is a whole other matter. They would see the head injury, and Fallon would accuse Adam, but Blake would probably protect him. However, I really hope Liam is alive.
My only other thought is everyone on this show is a terrible person. And yet I still like most of them.
