The monarch hatches, and the butterfly starts flying around inside the mini dome violently and creating expanding black spots where it crashes against the surface. These spots are mapped onto the big dome and begin to expand until both domes are jet black, casting the town into permanent darkness. Joe (Colin Ford) suggests the four touch the dome, but Linda (Natalie Martinez) cuts in, stating the egg is police property. The four choose not to stop her, knowing that she will be knocked unconscious and that this will allow them to escape. Junior (Alexander Koch), Angie (Britt Robertson), Joe, and Norrie (Mackenzie Lintz) then touch the dome together, and the mini-dome shatters, releasing both the egg and the butterfly. At first, the butterfly seems to hover around their prime candidate for Monarch, Barbie (Mike Vogel), but finally, they discover that the Monarch is instead Julia (Rachelle Lefevre).
