Stewie becomes a fan of Mary Elizabeth Becca Ryan, a rising popstar who used to be on his favorite show, Jolly Farm, much to Brian's annoyance. While at her concert, he posts a viral live tweet about her that she construes as an insult, resulting in her fanbase harassing him for days on end, even to the point of getting Rupert killed. Stewie later decides to confront her in person before she leaves her handprint at the Quahog Walk of Fame, only to find that she has already gotten over his comment and barely remembers it. Likewise, his speech falls on deaf ears among her fans, but he finds solace in the fact that Brian fixed Rupert for him. Meanwhile, Peter finds himself easily fatigued due to his weight and decides to get Lap band surgery, which leaves him with lots of excess skin. He decides to take advantage of his new body by spending more time away from the house, which disappoints Lois, who hoped that his weight loss would help him more easily bond with Chris. Peter ultimately helps his son win the science fair by acting as a human kite, only to be zapped by lightning and reverted back to normal.
