Hey, here's a silly question: What is the reading order between Ongoing and Countdown to Darkness? Does issue #20 of Ongoing come just before the first issue of CTD?
It looks to me from the previews and summaries like issues 18 & 19 were pure flashbacks, without anything set in the series present, and issue 20 looks to be the same way. So presumably Countdown to Darkness would fall in between the frame story of #17 (also a flashback issue but with a "present-day" frame) and the events of STID.
Although if you go by the stardates, apparently issues 11-13 take place in early 2259 while later ones are back in 2258. So they may not be progressing in linear order.
