The return of the exiled princess and the disastrous tea party of the Queen was the talk of the kingdom. Not only the gossip mongering nobles, but also the commoners talked about it and sympathised the Princess that how she had to bear all those insults hurled at her mercilessly by the allies of the Queen just because they felt threatened of their favour being reduced by the Queen. And when Princess Estia finally retorted back, she was humiliated with dousing her in wine. Though the nobles had different version of their narratives about the Princess being humiliated by wine or tea, the commoners didn't care about such confusions but went on with the wine version of the rumour.
It seems like the Princess has made her existence known to all the people in the kingdom just through a small tea party.
