Great chapter!!
Snape never expected Pompfrey to be so good with spells, its logical that she must be powerful, after all she is a healer and need to perform some dificult spells at the first try with no mistakes, maybe she can de-bone the hand of Snape to incapacitate him?
I wonder if Lily will be able to tell the Order of the trap before they fall on it.
Where did Snape send Harry? was a portkey to a Order safe place? It will be great if Hermione is the one find it him and rescue him.
Can't wait for next update you left us in a great cliffhanger.
Cheers.

With her knowledge of spells and counter-spells, I presumed Madam Pomfrey would be an exceptional dueler. Hopefully, the next chapter will answer your questions. Don't want to get ahead of myself.
