Now we know, the wraith's ship is gone.
The funniest line of the night goes to the scottish doctor. "Captain, it looks like you've picked up a klingon!"
In a personally funny incident, we were watching the ep and right after they got stuck and started having the debate on how to rescue, I paused it, said gee, all they have to do is move to the front of the jumper, and then when the gate closes they pop through. My wife and daughter disagreed. I unpaused it in time to have someone on screen say the same thing and someone else debunk it.
