A/N: Hey! So that wasn't too long, right? –tomatoes are thrown at head- Okay, okay, so it was. Fine. But here's another update.

Cass unlatched the skylight's clasp neatly and lithely swung inside, managing to land on the mattress, where she fell into an unhurt heap.
"I don't think you want to lay there too long," said Liir.
"I slept there last night, are you insulting me?" Nor asked. Liir cocked an eyebrow, and for a moment Nor and even Cass had no doubts as to the identity of his mother. But then he lowered it and the moment passed.
"No, I just think…I maybe might have been conceived on that mattress," Liir said offhandedly.
"Don't be gross," said Nor. "That's disturbing."
"No, it's the miracle of life," Cass said, giggling as she sprung off the mattress and onto her feet.
"It's not your father," Nor pointed out, shuddering. "Really. Could you be more insensitive, Liir?"
"I'm sorry my- Elphaba had an affair with your father before I was born? I'm sorry I exist?" Liir tried jokingly.
"Better," said Nor.
"Wait- what?" asked Cass. "What happened?"
"Cass, you're not the one owed an explanation here," said Liir. He folded his arms and tried to look intimidating. He failed rather badly, but neither Nor nor Cass had the heart to laugh at him.
"You really want to know?" Cass asked after a long moment. Liir and Nor nodded simultaneously, for another brief moment looking somewhat like siblings in the set of their faces and in their stance. Cass took a deep breath before beginning. But just as the first word left her mouth, the door opened and Elphaba and Fiyero entered.
"Liir, we have something to tell you," Elphaba said without prelude as she opened the door. But the moment she saw Cass, her mouth rounded into an expression of shock and the bags of food and necessities (they actually had bought some) tumbled to the floor.
"What the hell are you doing here?" exclaimed Elphaba. Cass looked at her guiltily.
"She was just about to explain that," Liir told Elphaba. "What did you want to tell me?"
"We got some food, by the way you're our son. Now what is she doing here?"
Liir gaped at Elphaba. "I'm- I'm- I am?"
"Unless she was having sex with someone else on the side, you are," said Fiyero, who had been watching reticently from the doorway.
Elphaba slapped him, but not hard. She whirled on her heel to face Cass.
"Now. You explain exactly who you are and what the hell it is you want from us," she demanded abruptly.
