Enterprise Destroyed By Death Star

Very disappointing explosion -- I'd think the antimatter annihilation would result in at least 1/4 the planet being destroyed. Also ... aside from the somewhat odd parking place for a starship, one would have thought there would have been at least a momentary "shield bubble" before they were overwhelmed.

So would there actually be any negotiation between BO and Darth? or would they pretty much be "on the same team"?
