Gillen picks up the story immediately where "Vader Down" #1 ended. Han leaves Leia in a huff after she refuses to help find Luke, while Vader (not surprisingly) makes short work of the Rebel troops that are trying to capture (or kill) him. Aphra stumbles upon Luke and disguises Triple-Zero as Threepio to capture him, hoping to win back Vader's trust (still afraid that he thinks that she purposefully sent him into a trap).
Really, that's it. In fact, the issue raises more questions than it should, given how little happens. Luke seems legitimately surprised to find the ruins of the Jedi temple, even though I was pretty sure that he knew that it was on Vrogas Vas and he got himself attached to the Rebel base there to find it. (I mentioned my confusion over this issue in my review of "Vader Down" #1. I guess that he really didn't know after all, even though I swore that he did.) Also, we have a weird moment here where Luke sees a light and dark image in the distance: he's convinced that it's Ben and his father, Anakin. But, how would he know that it was Anakin? He's never seen an image of him, as far as I know. Are we supposed to believe that he "feels" it? Gillen isn't clear, but hopefully we'll get more details later.
