The Gloom turns one's resentment and hatred into power. Voidera senses that The Gloom has begun to make its way for “the princess”. In the meantime, Summer has begun to feel like she is being watched from behind, but however, there’s no one watching her when she turns around. Summer starts to feel afraid, so Sly and Theo volunteer to act as her bodyguards. They butt heads from the start, but they still end up guarding her together as they do. Voidera is worried about Theo's lack of composure when it comes to the princess, and urges him to be on his guard, but Theo insists “Leave the princess to me”.
