It's hard to believe that what happened in this chapter actually took up the entire 30 (or however many) pages.
There were a handful of nice moments:

I was glad that we got some closure on the death of Ichiru; figured that they'd forget all about his body, so it was a nice brotherly thing that Zero went back for him as soon as he was able.
But overall, a lot of it felt like filler to me:

For example, the whole scene with Aidou and the Day Class girls? Way too long. It wasn't even an important enough scene that the mangaka needed to actually show it happening, in my honest opinion. Aidou could've shown up where the other vampires were and said something like "I just came back from the Day dorms and the girls said..."
But what I found especially troublesome and out of place about the scene was that it was filled with typical shoujo never say die simple-mindedness (i.e. the girls vowing never to doubt the awesome Night Class), and yet this came on the heels of Yuuki's "we can never be friends again" angst. It's like two totally different attitudes that don't belong in the same manga. Either VK is an idealistic manga where all problems are eventualy solved if we only believe hard enough, or it's a realistic one where things are presented as being more complicated than that. You can't just flip flop between the two attitudes however it suits you. It makes Yuuki look bad in that she didn't behave like an idealistic shoujo heroine and hug away Zero's troubles.
