I've only just got round to watching this.
Not much to add, though.
Paired with War Without End, I think this si my favourite, too.
I saw WWE first, and actually had to draw the timelines on a piece of paper to get my head round it :-)

As for the little things
I have always loved the breakfast scene - I thoroughly agree with Ivanova about mornings! it only occurred to me yesterday, that this was also about time, and time not quite being what it seems.
Not a true foreshadowing of course, but maybe a little nod and wink towards the subject of the episode...

And yes, I too started receiting the Ranger Code...
