2x20 - Little Red Dress
When Payton opens a box of photo's she suddenly remembers which day it is. Today is her mothers birthday (August 11) and her mood switches instantly. She is mad at herself that she didn't remember and Jason tries to comfort her a little. Something that at first doesn't seem to work, but eventually she lets him in a little. In the meantime Claire goes to visit her parents grave with Seth. She puts some flowers on her mothers stone and she talks to Seth about the picture she has from her mothers birthday where she and Payton are wearing matching little red dresses. We see a flashback to that specific birthday. Payton also tells Jason the story of this birthday after which Jason takes her into his arms and looks into her eyes. She smiled and nods at him. Payton and Jason then share their second first kiss.
