Ernie passed by Harry to go to the panel to the left of the sofa. He tapped it with his wand three times and spoke a soft spell, then watched as it sprung open to reveal a drawer containing a large variety of potions and ingredients. Ernie believed in being ready at all times, particularly considering how many of his friends were aurors who didn't like to visit St. Mungo's. "I know that," he replied with a smirk. "You like me for my cute arse and my cuddles too."
He made his way over to the sofa and snorted at the idea of Harry getting his arse handed to him by an 80 year old man. "Maybe that's why Voldemort failed, he was too young. Now hold still a moment while I run a diagnostic." The spell he wove was more in-depth than the one he'd cast a couple of weeks ago on Roger Davies - he saved it for the aurors who were too stubborn to list every injury they had, because it was hard to heal a claim of 'it's nothing, don't worry about it'. Once he was done, the spell needed a minute or two to explore Harry's body inside and out, but at least his friend could move a little until it was done.
"Two minutes from now and we'll know exactly what the damage is. In the meantime, you can give me the two-minute version of the tale - I'll get the rest when I get you drunk one night just so I can hear the rest."
