Penelope arrives alone at the banquet hall where the other debutantes are gathering. She successfully stopped Prince Astria from escorting her until they arrived here. Penelope doesn't want to make a commotion. If she arrives at their first assembly with the Crown Prince as her escort, then it will catch more unnecessary attention towards them.
When she enters the banquet hall, most of the young debutantes are already waiting inside. When those girls see Penelope, they all seem surprised and become curious about her identity. Only a few people know about Penelope's face because she doesn't like going out of their mansion if not needed. She always prefers staying inside her library, taking her lessons, or spending more time with her dad and grandpa.
