I had a feeling he'd start cooking something up after that, but the heads up is appreciated whether Layla is bullshitting or not. Yaxley's usually got his manbun pulled back too tight.
I'd still be wary about her, though. Maybe she does want to help. But I think with anything she feeds us, we need to be extra careful about it. Just because the first 3 bits of intel are good doesn't mean that it's not being carefully manipulated to pull us into a false sense of security.
