It turned out that Luna was just drunk.
Albeit it took a long time for everypony to figure that out with Luna actually firing at the crowd, at the guards, and of course at her own sister. But when she collasped after knocking over yet another buffet table, and the scent of strong apple cider was found on her breath, they marked it as a simple accident. The guards then hauled both of the princesses off to explain things to them in the morn. Since most of the guests had run off, and the ones who hadn`t were quite ready to go home, it was safe to say the party was over.
Starlight had just finished saying goodbye to her family, and was walking back to the castle with Sorea, when she remembered Thunderlane. She turned to her sister. "I have to go do something."
Sorea yawned. "Don`t be too long, okay?"
"`Kay," Starlight chirped, and flew off. She flew over the garden behind the ballroom, searching. Starlight spotted a dark blue figure flying towards her. There he is! she thought, flying towards him so they were hovering close together. Before he could say anything, she leaned forward and kissed him on the cheek. They both blushed, and were silent for a moment.
"Crazy party, huh?" Thunderlane said.
"Yeah, um, where were you planning on going tonight?" Starlight asked.
Thunderlane shrugged. "Just some random hotel. I`ll leave for Ponyville in the morning."
"Oh, okay." Starlight sighed sadly. "I guess I`ll see you later?"
"Definitely." Thunderlane smiled, and started to fly off. "Bye!"
Starlight waved to him. "Bye."
And as she flew back to her quarters, she allowed a little seed of hope to plant in her heart.

She felt wet and cold. When she shifted her body, rocks seemed to pierce her at all angles.
"Wha-?" she murmured. Luna`s eyes fluttered open to see a large rat staring back at her. She jumped up off the ground, frantically looking around her.
"WHAT THE BLOODY HAY AM I DOING IN THE DUNGEON?!"
