Really, Caspian should have noticed it from the beginning.
This maid in the house - she's different from the rest. A lot quieter, doesn't hide away in the back alley with the other servants stealing smoke breaks and trading gossip. Her hair - it was always tucked up in a linen bonnet, but one day he catches a glimpse of it, a golden lock straying and framing the side of her cheekbones. A delicate, pronounced affair.
