//Raven’s power will continue to grow exponentially until she’s finally powerful enough to consume all of creation.//
That made me laugh. I'm sure you didn't mean it to, but it sounds a little...comicbookish to me. I mean, 'consume all of creation'? That's a little...you know.
Also, does Donna really talk like that? I haven't read her much, but I don't remember her speech being so formal. Usually I saw her talking like any other person, and I'd assume she would type a message the same way she would talk.
I think you are using the dialogue too much to carry the story. There is some stuff that would do better as narration and you have almost no descriptive narration. You seem to only be using it for actions and character placement, almost like in a script (but not THAT bad). What about feelings? What about plans? What about people's observations of what goes on? You have almost none of that in this chapter, and possibly others. I'd like to see a lot more of what is going on in their minds so I can connect with them. So far, I can't really connect with your characters.
//there sat Wally, his head thrown back, mouth wide open and snoring.//
Okay, this gave me a laugh too, but in a good way! Nice.
//Her voice became more stern//
I'd be careful with sentences like that. 'became' is not the best word to be using for a sentence like this. I'd go with 'Her voice dropped an octave' or 'Then, more stern'. I don't see 'became' like that in many pro books and with good reason.
I like the exchange between Cassie and Tim. The Batclan is always baffled when people who know them well can read them. XD
//My God! One second she’s saying she has feelings for me then she’s crying over Connor. What the hell am I supposed to do!?//
Okay, this is just freakin' hilarious! I love these misunderstood comedies. Rofl.
I've seen 'looked' used way too many times. There is also glanced, stared, gazed and a few I've forgotten. That isn't the only one, but it stands out the most. I'd also like to know what the Javelin looks like. I know it's big, flies and not as cramped as the Batjet. That's about it. (from your story)
Btw, you need some kind of indication that you changed scenes. It jumped from the freezing Arctic straight to Africa. It looks like they are all in the same spot!
//used for something that she hates//
Oh come on! You know how persuasive Bruce is! Hates? He use a phrase like 'loathes with every fiber of her being.' or something stronger. He's having to justify something that looks like murder. He isn't just convincing them, he's convincing himself too.
//but let’s face it; we’ve fought against reality-bending psychopaths from outer space, so this really isn’t that much of a stretch if you think about it.//
I think adding the justifcation for that twist was a little much. You were better off with 'Crazy, huh?'

All in all, this is exciting, but I can't get into it without something to connect to. Otherwise it's just a radio show.

keep adding more i'm loven this story!LOL

YOU ROCK!XD

Aside from some minor nitpicks and the ambiguous speakers, this is really well written. Raven turning on them is a nice twist...I wonder why she did that? ;)
I look forward to more of the story!
