I think it was the ribbon or something that Jennette gave to Athy (when she wore that sailor dress) that caused this to happen. Not because Jennette had ill intentions, she would never, but it was because of Claude's brother (the black haired dude) put magic on it when He and Jennette were talking in the store. (Just to clear the confusion where people think Jennette is the cause!)
I'm honestly really glad Lucas is here to fix all the problems and can hopefully expose the rat who was behind all of it. I feel really bad for Jennette though because she really does want a family and have no intention of harming Athy or Claude or anybody for that matter.
Okay but, Lucas looks good fr. He's so adorable that he'll literally smack some sense into Claude for hurting Athy (As he should)
