Just a few thoughts:
1. I'm probably having a brain freeze on this, but ever since the adoption of the new roll call silhouettes in #16 I've been unable to identify one of the Legionnaires. The figure is in the bottom panel standing between Saturn Girl and Timber Wolf (in #17 between Saturn Girl and Brainiac 5). It's not Dream Boy and it looks vaguely alien. Any thoughts?
2. Shrinking Violet is allowed to use a weapon? That's disappointing.
3. If a Naltorian -- say, Dream Boy -- announces what a person's about to do in the future and thereby stops that person from doing it, isn't that a new take on the long-held Dream Girl theory that Naltorian predictions always come true? In #18, Dream Boy predicts what Brainy's about to say, but doing so prevents Brainy from ever saying it...
