Whilst eventually becoming one, she sabotages them. After conflicts involving Regina's ex-boyfriend, Aaron Samuels, Cady later becomes tied between being part of them or sabotaging them. She becomes a hit with the Plastics and eventually assimilates into the clique, only for Janis to ask her sabotage them. Cady is warned to avoid the "worst people you will ever meet", the Plastics-a clique comprised of three girls: Gretchen Wieners, a girl who's rich because her father invented toaster strudel Karen Smith, the "dumbest girl you will ever meet" and Regina George, the unofficial leader and the meanest one. Attending a Chicago public high school for the first time, she starts out by befriending the "best people you will meet", Janis, a supposedly lesbian girl and Damian, a boy "too gay to function". Her parents being zoologists, homeschooled Cady Heron lived in Africa for 15 years. However, when some policemen try to arrest her, an unknown energy repulses them. Thor then returns to Earth just as Jane reappears. Thor learns from Heimdall, who can see into all of the realms, that Jane disappeared. Back on Asgard, Thor wishes to return to Earth but his father, Odin refuses to let him. She goes to investigate, finds a wormhole, and is sucked into it. Jane discovers an anomaly similar to the one that brought Thor to Earth.

In the meantime, Thor has been trying to bring peace to the nine realms. In the present day, Jane Foster awaits the return of Thor although it has been two years since they last saw once another. The warriors find the Aether and since it cannot be destroyed, they try to hide it. Warriors from Asgard stop them but their leader Malekith escapes to wait for another opportunity. Thousands of years ago, a race of beings known as Dark Elves tried to send the universe into darkness by using a weapon known as the Aether.
