Hmmm, a time skip... my opinion of those is that they are a delicate thing to handle... but I do feel that this story in particular may have a good profit from using it.
If Diana is the focal point of things to come, it may be better for the narrative for us to see her already a little older, so that she can truly react to what happens around her.
And I have to say... just seeing Julian with a happy smile warms my heart... but with the dumb bitch and her goon squad on the prowl, the question is how much time that will last.
One way or another, now things can truly pick up, we got a hint about what Diana may be and how at least the abilities are distributed... now let's see how things go.
