That would really suck to have Malcolm killed so soon.
I think he'll end up somehow in a coma for a few issues (maybe even the entire next story arc)but eventually he'll come back.
As for Bittner, for some reason, Hock already knew Sevara wanted to 'defect' and switch alliance so he decided "Screw it! If I lose you lose too!".
Thankfully, Sonja survived.
Next story arc, Carlyle is without real leader, for at least a while. Eve should have cut Jakob Hock's head off. Damn you Hock, damn you!
