I've been busy, okay?
I'm working on various school projects, I'm heading to high school in a couple months, so we're getting prepared for that, I'll start marching band sometime in May, and I have a really big test to worry about in March.
So, Nightwing's not likely to be on as much as he'd like to be for the next couple months. Yes, I said months. You should be seeing a little more of him in October, when marching band season ends.
