Amusingly enough, Agnes's wasn't the only who was being glared at by a relative, Iris was also being given an accusative gaze by Layla, since the red head girl omitted Espi's existence when she told Layla about what happened at Esmeralda's realm.
The three maids feigned ignorance and looked away when Layla also stared at them, rendering Layla speechless, ultimately, she could only give in, she knew that Iris was quite a straight forward girl, if she was shown kindness she'll repay it to the best of her capacities.

The previous also drew Valentina's attention towards Layla, while she guided everyone out of her office, she didn't forget to say.
