I feel like Ron would try and make an attempt to reach out to Hermione to "save her" in his mind but I think after she rebukes his claims and attempts, he would surely move on and decide she's too far gone to see how dangerous it is being so close to Harry since he continued to put so many in danger and now with the TT underway, he could feel as though Harry is just doing it on purpose for fun, and that he doesn't see Harry as a victim but maybe someone just taunting the idea of luck and how far he could go. Let's not forget Ron did miss out on the night's adventure when they saved Sirius and battled dementors by the lake. I assume they may have mentioned it to Ron later (or not) but it could only back up his own delusion that Harry is reckless and while a good person, is going down a dark park (ironically).

I figure Draco seeing Ron decline in mental stability would pique his interest greatly but it would get old after a while. And I assume if Draco continues to belittle Ron, Ron might actually stand up for himself and maybe in that confrontation/fight, Draco could see what he could become: a crazy misguided redhead. XD I will say Ron's reasons in his own mind make sense and that he considers his actions to be for the grater good. I think playing him as more complex would be a fun change. I am unsure if Draco would join the D.A but if he did, he would need to be welcomed in a way that doesn't kick up a lot of crap from the past. If he has a decent or strong enough friendship with Luna at that point, he could certainty join and begin to make up for the stuff he has done and in a way, Ron and Draco could switch places. 

And Ron joining the Inquisitorial Squad would be a big change and surprise. I think if we reeled Ron back at some point (when he becomes a full fledged Death Eater) so his connection with Harry, Hermione (probably Luna and Draco by association if he's tasked to look into why Draco's pulling away from the Dark Lord) is repaired to serve him much like a double agent. We don't want Ron's credibility to be completely invalid so quickly, after all. But if Draco joined to keep an eye on Ron...oh. Upon re-reading, I wasn't sure which he was either Ron or Draco. Sorry.

I think Ron could still join the D.A but to just keep tabs on Harry and everything and pretend their friendship is back on track. Or Ron could join the I.S as well, as I mentioned, Draco on the other hand, would depend on how well he is with the general core cast and how much contemplation he's done in regards to his own future and safety. Maybe he trusts Harry more now? Same with Luna. 

I figure I could play Ron, unless you ever wanted to use him during your posts for something...?

In terms of where/how to start...should we begin with the first meeting for the newsletter? Or sometime before that? And we know where Draco and Luna will be? Should I assume Harry and Hermione would be practicing or maybe with Luna? I know Hermione would want to help with the newsletter since it sounds right up her alley, even if she is busy helping Harry. But our roles don't have to be together all the time or even most of the time but I think it might be good to try and bring them closer at some point so when things start changing and happening, they may be stronger together.
