Re: LENA'S ORANGE PEEPS.
Loki's no healer, but he's definitely powerful enough in sorcery terms to be able to at least bring Harry back from the brink and not die if that's cool with you? Maybe one of those 'he's skilled but it's also in the middle of a huge battle so he only had time to patch him up and keep him stable/get him to safety' kind of thing.
