Luna snorted in rage and tossed the tree back over her shoulder as her foe dissolved. A second later, she turned into a starry mist herself, only slightly different from how Nightmare Moon had done it. She wasn't fast enough to get into the ground after her before Celestia's shield spread over the grass, though - and, to be fair, she wasn't exactly sure what'd she'd expected to do if she did find her like that. Mist was fine for travel and occasional object manipulation, but she wasn't going to be dragging the Nightmare back to corporeality like that.

Reforming, she merely bristled at Chell's words; she'd been so focused on the Nightmare that she hadn't even noticed what happened to the others. Rage tended to give her a bit of tunnel vision.

"Thou hast no idea." Really? You're going to lecture her about being disharmonious when she's fighting against Nightmare Moon this time? When she tried to drag the sun up on her own, to end her own night? What more does she have to do? The blast of magic she sent towards the Komory Bat swarm might have had rather more force than was usually necessary to destroy such creatures.
