Wally West fans were delighted to read "The Flash: Rebirth" #1, as its story picked up right where "DC Universe: Rebirth" #1 left off for the finally-returning character. Those fans will definitely want to buy "Titans: Rebirth" #1 as well, as it continues to follow Wally's new trajectory even as we also find out what's next for the classic team after "Titans Hunt" #8's grand finale.
If you thought the surprises and revelations were set to slow down as DC went into Rebirth's second lap, think again. In this issue, Wally West not only gets reacquainted with some of his old teammates, we also learn updated memories and status quos for five Titans members as Wally's touch sparks what was erased from their minds when the New 52 arrived.
Roy Harper's time as Green Arrow's sidekick Speedy is made fully explicit here. In doing so, it helps lock in the idea that this is more than just memories being uncovered for these other characters. We'd known that Wally West was a refugee from the post-Crisis DC Universe (which this universe's new Superman also hails from), but the dividing line between those two universes seemed concrete. Now, the barriers are starting to blur; there's no way for Arsenal to have been Green Arrow's sidekick in this universe, to say nothing of Wally working with Barry Allen. It's almost as if rather than regaining suppressed memories, this universe's Arsenal has been instantly replaced with that of the previous universe when he and Wally touched.
Lilith's time with Wally is also revealed in "Titans: Rebirth" #1, although in this case it doesn't click into place in the previous universe's continuity. Lilith Clay's new history includes having at least a brief romantic interlude with Wally West, with Wally serving as a voice of comfort when Lilith's powers were running out of control. Considering that Lilith's past romantic affiliation was with Gnarrk -- who is curiously the only Titan from the final diner scene in "Titans Hunt" #8 not represented in "Titans: Rebirth" #1 -- this is a major change from any previous interpretation of Omen.
