zgirnius:
I don't find Snape's reaction requires any special explanation 
involving a plan with Dumbledore. In light of what he knows, it seems 
to me that his first thought upon hearing that Death Eaters were in the 
castle would logically be that Draco brought them in. Even without 
advance plans that Snape must kill Dumbledore, seeking out Dumbledore 
and Draco first to see what is happening seems the correct decision on 
Snape's part to me. There are other Order members attempting to deal 
with the battle. There is no other Order member who knows what Snape 
knows, so it makes sense for him to leave them to it.

I'm not saying the plan theory is wrong. If Dumbledore had been dying 
slowly all year (an assumption, he might not have been), for example, 
it would be very logical and consistent with his character to come up 
with such a plan. It would also be a reasonable worst case scenario for 
him and Snape to consider. It could have been the subject of the 
argument in the Forest. On the other hand, Dumbledore did not believe 
that Draco could get Death Eaters into the school, and he did not 
beleieve that Draco would kill him. So it is not necessary, in my view, 
that such a plan should have been discussed in advance.

Personally, I think the plan they dicussed in advance was a plan to 
talk Draco out of the killing and offer him and his family asylum. A 
plan we appear to have seen in action on the Tower, which failed due to 
the arrival of the other Death Eaters.
