DC has stalled in releasing digital back issues of the flash and Impulse. It’s been a few weeks since the last update, which is unfortunate since both series left off in the middle of a story – Flash in “Chain Lightning,” and Impulse in the beginning of “Dark Tomorrow.” I think they’ve stepped up the Superman releases to tie in with “Man of Steel.”

The Flash doesn’t star in any new comics this week, but ComiXology has added two new backissues to their digital library:

Flash #148: “Chain Lightning” Part 4 – More and more future speedsters join the fight as today’s Flashes travel through the next thousand years to battle Cobalt Blue. But one Flash remains: does Wally West dare risk contacting Barry Allen?

Impulse #72: Forces unknown kidnap Carol, and Max Mercury battles an enemy from a former lifetime. Major changes are afoot in this lead-in to “Dark Tomorrow.”

Lots of Flash comics are out this week!

Flash #20: “Reverse” Part 1 of 6. An all-new Flash epic begins here, and the stakes have never been higher as Barry races toward a confrontation with the Reverse Flash! Preview at Kotaku.

Justice League #20: The PROLOGUE TO TRINITY WAR continues as a revelation about Batman could destroy Wonder Woman and Superman’s relationship! Plus, in the backup story, the penultimate chapter of the tale of Shazam finds Billy Batson learning the shocking secret of Black Adam! Preview at CBR.

Justice League Dark #20: The Flash and Swamp Thing guest-star as the team struggles to recover the stolen House of Mystery from Dr. Destiny! Preview at CBR

Teen Titans #20: “Light and Dark” continues as the fallout of last issue’s attack threatens to drag the team into darkness! Preview at CBR

And in digital back issues at ComiXology…

Flash #147: While traveling the time stream to prevent two future Flashes and Barry Allen from falling prey to Cobalt Blue’s magical gem, Wally West runs into the Reverse Flash. “Chain Lightning” part 3. Preview/buy.

Impulse #71: Lucius Keller–one of Max Mercury’s oldest foes–has returned. Meanwhile, Impulse and Carol discover some strong feelings for each other, but this revelation comes far too late. Preview/buy
