I don't see Justine as weak, but I feel like the scenes in which we've been allowed to see her lately have been unfortunate choices of Butcher's, if you know what I mean. We've seen her playing the bland assistant role, and even though I *know* she's being an undercovery spy, she doesn't get to actually do much that's interesting on-screen. But I was still on board until that stupid threesome, which just really pissed me off on both a worldbuilding level and a character level and a Butcher-writing-women-in-this-verse level... :(
