Four scans from Planetary #27, which I can confirm does exist.
This one's a wrapup issue, as Planetary has won the war, is changing the world, and Snow turns his attention to Ambrose, the black guy who died first, many, many issues ago. Since his power was time manipulation, they believe he froze time shortly before he would have died, and is thus stuck in a bubble of frozen time from which they aim to rescue him.
To do this, they enlist the aid of what I'm sure if very well-researched by still very impenetrable theoretical physics/technobabble (in my Warren Ellis comic? Well I never!). While Drums and the nerd squad do their thang, Jakita is frustrated.
The imaging reveals that he is in fact there, so they go about building a time machine to get him out.
The use of this machine carries its own inscrutable techno-dilemma, which, as near as I can understand, is that using a time machine will instantaneously create the future, which up until this point exists as a series of Schrodinger's Cat possibilities. Or something. Elijah doesn't care, and assumes the future will sort itself out.
I was never as big a fan of Planetary as some people were (often, the concepts Ellis was using were a lot more fun than anything he actually did with them in the story), but this is a solid epilogue (though I'm sure some people will understandably, given the length of production time, be expecting something bigger and louder).
