“Rush is still at it in the second season,” Carlyle said, “but even more so this time. When we join the second season, we discover instantly — in the first two or three scenes in fact — that Rush has discovered the bridge of the ship. Not only has he discovered the bridge, but he knows how to fly the thing. He’s steering it around. [The others] don’t know that. He hasn’t told anyone this.
Carlyle revealed that the rest of the crew is kept in the dark for some time, and it won’t be until episode seven — “The Greater Good” — that Rush’s secrecy is revealed. “Rush and Young go investigate an abandoned alien craft which is just outside the Destiny,” Carlyle explains. “When they’re over there, it hits the fan back on [Destiny]. They find the bridge. They find Rush is responsible for all this stuff. “That puts Rush in a difficult position, as you can imagine, because the last time he was left with Young anywhere, he left [Rush] on the planet.”
Moving forward, the relationship between Dr. Rush and Colonel Young will move in a new direction. After Young learns the truth there is “an 11-page scene between myself and Colonel Young,” Carlyle said. “It’s tremendous, and it’s something you don’t normally get in television — followed by a 6-page scene after that, where Rush explains everything to [Young] and confesses.
“But, not only that. There is, in fact, a mission. There has always been a mission. It has never been about going home. It’s a game-changer, as they like to say around here. Everything changes in that moment.
“So Young, instead of wanting to kill [Rush], says, ‘What is it?’ [Rush] tells him, and it’s so mind-boggling he actually manages to get Young on [his] side. The dynamic changes between Rush and Young in that moment. They decide to come together and move forward. Don’t start looking behind. Stop saying we don’t belong on this ship. Embrace it, and move forward.”
“But is Rush telling the truth?” Carlyle added

I wonder what the mission could be...
