Again, even if they always feel different and V, who is only just starting to pay attention and so might not be that practiced at noticing subtle differences between conscious and unconscious intent over the link, noticed, who's to say Blackwing didn't do that before? Which is more likely? A running gag playing off one of Blackwing's character traits when the strip hasn't had humor for several updates, or V reverting to old behaviors that s/he is over a book past? Especially when one of the comic's main points is on the merit of growing and changing.
Dismissiveness isn't always callousness. And honestly I don't see the point in always assuming the worst of V.
