Beckett: They think the gene was used as a sort of genetic key, if you will, so that only their kind could operate certain dangerous and powerful technologies.
(Beckett turns away from the Chair. Behind him, Sheppard pokes at the arm control panels tentatively.)
Sheppard: So some people have the same genes as these Ancients.
(Sheppard walks around the Chair.)
Beckett: The specific gene is very rare, but on the whole they look very much like we do. In fact they were first. We're the second evolution of this form, the Ancients having explored this galaxy for millions of years before ... Major, please don't.
(Sheppard started to sit down in the Chair.)
Sheppard: Come on, what are the odds of me having the same genes as these guys?
(As Sheppard sits down, the Chair immediately lights up and reclines. Sheppard and Beckett stare in amazement.)
Beckett: Quite slim, actually. (Shouting out) Doctor Weir! (looks at Sheppard) Don't move.
(Beckett hurries off. Sheppard lies in the Chair, looking upwards nervously.)
