significance of Scar's Ninja Sticker

The laptop sticker of a ninja that Scar gives Jessie symbolizes Jessie's fighting spirit and unwillingness to be a victim any longer. Up to this point in the story, Jessie has been conflicted and lacking confidence in herself. However, she regains a sense of herself after the weekend in Chicago, and the sticker, or laptop tattoo, symbolizes her ongoing desire to maintain that feeling even in the unfamiliar environment of LA.
