For all that I feel I should weep at the end of this, I can't help but smile. This is just so poignant and sweet; I'm glad the boys got to choose their own time and place to end it, that they are truly not immortal. And to become a part of the Big Bang and perhaps start over to find one another again... priceless.

It is such a Ianto thing to keep a meticulous list on where and when Ianto and Jack end up in their travels. And I like that it is the death of the Doctor that has them make the final decision to end it all.

Truly a beautiful way to end their journey.
