So, This is my understanding right now:

Maddox showed up, killed Beatrix, threatened Mayt and Damian. Then Damian went ham on Maddox.

And, back with the rest, Master Jamie is being abducted by a legion and Sasha is trying to save he/she/him/her/it

Also, J8cob, is there any chance at all of possibly saving Edo-Beatix's life?
