Message Dart to Madam Pomfrey and Healer Weasley in the Infirmary

[limokolax]

I am on my way to the infirmary this moment, but I must ask that you cease and desist your treatment of Albus until I've arrived. I'm certain I've uncovered the root of his illness, and I'm afraid his situation is more dire than we've ever suspected! I'll brief you completely in a matter of moments.
