When Angela and Wesley are sitting at the table, right before the end of the scene, the size of the pickle that Angela dips changes. At first, her hand barely stayed out of the dip and then when she pulls it out, it's almost a full size.
Wesley tells Angela he is predisposed to Fragile X syndrome but that's not possible. Fragile X is a problem with the X chromosome. As a male, Wesley only has one X chromosome. He would have to actually have Fragile X himself to risk passing it on to his child. Since he doesn't, there is no increased risk or predisposition.
