When a maid suggested Alicia spend the night at Harold's chamber, she had a feeling that the water incident was not as simple as it seemed because the whole story made no sense and wasn't adding up either. But the thing she didn't know was whether this was purposely done by the maids or someone else.
She didn't think this was Harold's doing because he didn't seem like the type to be petty like this. So she assumed they probably had a shipper in the palace who wanted them to become closer. And thought doing this was going to set their plan in motion. Unfortunately for them, she was neither stupid nor interested in Harold. She had visited Princess Tyra's room instead and had seen the surprise in Tyra's eyes when she opened the door.
