Priscilla totally knew that Robert was happy and that he wanted to jump up and down from excitement but by the way he looks, he was controlling it. It was a disappointment because she wanted to see how he reacted, probably was adorable or something. But she wouldn't worry, he is gonna have to show her his adorable side sooner or later. So that reaction that he was holding within, it had to be let out. 

Yeah, Priscilla was hungry, hello she raged and threw away her food. Very regretful. [color=pink]"Hey! I was only raging because of what she said. No no no, it wasn't because of what she said. I just didn't want to see her...! For godsakes, Robert my underwear was showing! Half of the people saw it, I think."[/color] her panties were colored pink, clearly because she loved that color. 

As they were walking, she reached for an apple from Robert's tray and as soon as she placed it on her mouth, the bell rang. Crap...she took a bite out of it, turning her head and seeing Greyson there. [color=pink]"Hey Grey! Yeah, I have Grimm Studies as well. So we all go! Come on!"[/color] Priscilla nodded taking another bite as she winked at Robert, now walking ahead of them to her classroom.
