Alice was detained in the dungeon under the castle as per Princess Swan's order. The cat maids accompanied her until she got locked up, and once she was inside the cell, she asked them, "Myra… Maya, you two should believe in me. I was forced to do it, and I don't know what to do, because nobody wants to listen to me!"
The cat maids looked at her with a complicated gaze.
On one side, they wanted to believe her, as they knew that Alice was probably the most lovable and popular maid amongst the servants. She was lovely and cute, and she truly dedicated herself to serving His Majesty.
But they also understood their Princess' stern order. What Alice did was truly dangerous. She could be executed right now and nobody would even defend her because poisoning their Beast King's wives was a treason against the Beast King himself.
