This was an awesome episode.
First off I wish to start back to front this week and talk about the ending. A real hollywood ending or what. I am sure that if they make a space version of Titanic they will just copy and paste the ending of this episode as their own. It was so dramatic and the way the Destiny just fell into the sun and how it looked as it was being smelted down into its core elements was absolutely stunning.
This epsidoe was full of intrigue, despite using an already used plot (time travel) it seemed to actually fit better in this episode than the original one they used it in.
We saw yet another aspect of Rush here, his ability to die with his dream. It also says something about how he feels about his life back on Earth (maybe he considers that existance dead?).
The shock on Elis face as he saw the other destiny and the big gaping hole in the back gave the moment a lot of atmosphere (they really paired it well with the music and the camera work).
This episode had some more ironic humor and twists in it, for example when Rush turned around after the initial conversation and said "well at least now there is some one to have a meaningful conversation with" That line made me laugh a little and it made me laugh because I knew Rush and I knew him well (thanks to the boring character building at the start).
The confrontation between the other Rush and the Col was to be expected, Young had made allowances but he hadn't. Everyone knows that when you push Rush into a corner he pushes back. The look of grief on his face really told a good side of him, that he can do sly things but he could never kill someone (unless they kill his girlfriend :P).
Overall this episode was just as good as last weeks. Loving it, going to miss this show :(.
