This One Time at Space Camp... (S04E18)

The Astraeus clock is ticking as the nervous candidates appear before Senator Wen (Ming-Na) for their final evaluations. One by one, each aspiring crew member is fitted with a memory reader to reveal their deeper motives. Warren Hughes (Wallace Shawn) uses the same device on Carter (Colin Ferguson) and Allison (Salli Richardson-Whitfield) as part of their appeal to his ruling against their relationship – although he warns them not to expect a reversal of his decision. Many facts come to light in the Astraeus interviews. Senator Wen learns that Holly (Felicia Day) has been an over-achiever since birth, Zane (Niall Matter) learned to improvise -- not always legally – as a lonely teen, Fargo (Neil Grayston) has always had more smarts than he's been given credit for, and Jo (Erica Cerra) is obsessive about rising to a challenge. A series of bizarre attacks around town threaten to derail the Astraeus mission, the acts all the more mysterious for appearing oddly familiar. When Carter realizes what is happening, he takes Henry (Joe Morton) on a hair-rising ride to save the life of the man who set out to destroy Carter and Allison's happiness. (iTunes)
