“Bo Peep is intro­duced as Woody’s love inter­est. When Andy is play­ing with them, he makes Bo Peep the damsel that Woody must save. Lat­er, she offers to get some­one to watch her sheep, with the inten­tion of spend­ing time alone with Woody. She is one of the very few toys in Andy’s room who believed that Woody would not inten­tion­al­ly harm Buzz when he acci­den­tal­ly pushed him out of the win­dow, although when Woody expos­es Buzz’s sev­ered arm, she begins to doubt him while the oth­er toys are more con­vinced to take Mr. Pota­to Head’s side in turn­ing against Woody.”
