An Oath Made, An Oath Fulfilled

Severus Snape is confronted my Minerva McGonagall in the Great Hall. Severus must decide whether to fight or flee. A decision is made that sets a greater plan into action. 2 Part only story. Snape hurt/comfort, angst. Set in DH Part 2, this is a rewrite of this great scene to cater to some different themes. No slash, whump/angst only.
