After one is caught in another cave in, the remaining three make their way to a gate but must jump blindly from planet to planet hoping to pick up a signal from the Destiny before it jumps. On board the ship, Col. Young decides to send out a search party. The clock is ticking down and the next jump will take them into an inter-galactic void forever leaving their friends behind. TJ meanwhile decides the time has come to tell Col. Young that she is pregnant with his child.
