Emma might've been smaller than Luna, but she was wiry and she was bloody well strong enough. She wedged her shoulder under Luna's arm, more than willing to take her weight as they moved towards the Apparition point. When someone tried to get in the way, Emma snapped, "Oi, head injury. Get your sorry arse out of our way, yeah?"
She leaned her hip into Luna to help hold her up when she felt her weight slump. Bloody hell, this wasn't good. "Just hold on tight, yeah? Apparating with a head injury is bloody well awful. Um. Lean forward a bit. It'll be simpler when you puke, yeah? Sorry, but I can't make it better." She tightened her hold, and twisted in space to take them both to St. Mungo's.
