Lately, Harry had been trying to learn a very advanced kind of magic. It was a magic that was well beyond ordinary wizarding levels, and when attempted, it could drain a lot of the user's energy.
And in the case of Harry, it was no different. During one attempt at using this magic, Harry had fainted and he had to be tended to by Madame Pomfrey. After Madame Pomfrey had left him to rest, his girlfriend Susan showed up to check on him.
"Are you okay, Harry?" Susan asked him, giving his hand a gentle squeeze.
"I'm fine," Harry insisted.
