This is from Blackest Night: Titans #1, by J.T. Krul and Ed Benes.
Thanks to Black Lantern!Lilith, Gar thinks he's kissing a normal Terra. Then... I wonder why Terra II isn't mentioned and Gar just assumes it's the original. And yes, Robert Long was a toddler when he died, not a baby.
Meanwhile, Black Lantern!Hawk takes on Holly and Dawn.
I'm really disappointed we didn't get to see Black Lantern!Terry Long. Hopefully he shows up next issue.
