'For a moment there I thought we were in trouble'
Regarding this quote from Butch Cassidy and the Sundance Kid. What do you guys think the significance of this was?
I thought is was a double meaning used by the writers. One the quote refers to an ending that is an open ended tragedy referred to as a Bolivian Army Ending (i.e. the viewers are left to decide for themselves what happens...do they live or die just like in Butch Cassidy). And that is exactly how the episode ends - with the viewer left to decide the outcome. In addition I think Rush says this to indicate that his own fate after stepping through the wormhole is unknown and left for the crew / viewers to think about what happened.
On the contrary it could also be that he actually meant it literally, meaning Rush thought they were in trouble but really he was relieved because he realized they were not. This example may be of further indication that Rush knows more than he letting on (i.e. he knew he would survive through the wormhole and it was caused by a solar flare, possibly even knowing it would send him back in time -- assuming he was able to determine this using the ships computer beforehand)
