She started to treat Katie better when she thought she had cancer and did the same with Alexa when it was her the one who had the illness, but told her “I’m only treating you like this because I won’t stop being popular”. Alexa doesn’t like being treated kindly by Gwenny because it is not her real personality, so she achieves to make her hate Alexa so much that she goes again to her normal behavior.

Season 2[]

In the episode #GWENCAS, It is known that Gwenny and Alexa's brother, Lucas, go to Cooking Class together. Gwenny doesn't like Lucas, but Katie doesn't agree and finally, for Alexa and Katie's disgrace, Gwenny and Lucas become a couple. When Gwenny comes to Dave, Lori, Alexa and Lucas's house, she brings cupcakes. All the family is surprised about how delicious the cupcakes are, and she says they were baked by her.
