"Absolutely," Lyle purred. "Do you think the Capitol has noticed?"

This situation required delicate handling. He didn't want to reveal his pro-Tribute rebellion sympathies, nor did he want to damage his cover as the kind of sentient who didn't care about anyone other than himself and his team. On the other hand, he also didn't want to shut down the possibility that they could be allies enough that she might trust him when then plans started rolling on their own.

So: a warning about protecting herself, garnished with a hint of a threat that he'd noticed and might not have her best interests at heart. At least, that was what he hoped came across. Better from him than from someone who wouldn't die before selling her out, right? (Not that she knew about that guarantee, yet...)
