When Haley sees Dylan on the bike then goes back to Ethan the cotton candy goes from full to almost fully eaten
After Ethan pushes Dylan down, Claire runs up to Ethan. Ethan has nothing in either of us his hands. The camera angle changes a second later and he is holding two corn dogs in his left hand.
In Season 1, Ep. 14, "Moon Landing", Claire tells her friend Valerie. "Haley is 15, Alex is 13 & Luke is 11". In this episode she tells Jay, "I think I inadvertently set my 14 year old (Alex) up with a college boy". If Alex was 13 in Feb. 2010 she couldn't be 14, twenty-eight months later in May of 2012.
