Also, Sylar teams up with Elle to try to capture Clare to bring her to Pinehurst to give her to Suresh to experiment on as the missing catalyst to the formula. But everything changes when a prolonged solar eclipse happens, which renders the heroes and villains powerless, stranding Peter and Nathan in Haiti with the Hatian who is trying to capture the powerful Voodoo witchdoctor Baron Samedi. In Kansas, Parkman must find a way into the Millbrook house without his mind-reading powers, and learns what Daphine is without her super-speed powers. In California, the powerless Elle and Syler try to capture Clare, who accidentally gets shot, and Nathan seeks revenge.
