YMMV / Star Wars: Crucible

• Fridge Brilliance: Vestara's Motive Decay may make sense when one thinks about her Heel–Face Door-Slam. She's sunk fully back into the Dark Side, probably more than she ever was before, and has nothing left to live for, with her people all dead and Ben hating her. Of course she's gone into Chronic Backstabbing Disorder and trying to get as much power as she can. That's all she's got, now.
  • Also, at the end of Fate of the Jedi, it was implied that she might join up with the One Sith. However, this too is Fridge Brilliance: Having had a taste of the Light and how addictive it was, it makes sense she wouldn't want to join up with a bunch of Sith who remind her of the Lost Tribe. It's also possible, if not probable, that she still has some feelings for Ben.
