"My mom is interested in his money," Lyra said, wishing she had pockets to shove her hands into as well. She'd decided not to tell her mom about the Archer and Rosario connection when she'd told Jocelyn, cuz if Jem knew Rosario's bio-dad was as rich as his son, she'd be on at poor Carla to hunt down AG2 and squeeze twenty three years of child support out of him, and neither Carla nor Rosario needed that in their lives. Jem had been bad enough when Lyra had mentioned Archer had his own helicopter (and how could she not mention that, back in the beginning?)
"Mom learned he was some rich heir and she just latched. That's all it was, serious." She was getting a bit worried at his grump, though she was too tired and hungover to be sympathetic if it was stemming from any place of inadequacy. She wasn't gonna try and placate that part of it, or anything.
Still. "I didn't tell you cos I was embarrassed bout being charmed, that's all," she admitted. "And we'd just met. So suck it up. And believe me when I tell you I am not interested in him. Not romantically or sexually or anything like that. Okay?"
