1. What are the current plants with GA? I remember reading that Dan Didio the man who doesn't like sidekicks, said that Oliver would play an important role in the DCU which was I guess the reason that his solo series ended. Looking at the website Comicbookdb.com looks like in August Ollie's having a team-up with Green Lantern and I think he had an appearance in DCeased? Hopefully his solo series comes back sooner.
2. Roy Harper/Speedy- Yeah he's currently dead but I imagine he'll be back at some point, hopefully soon. I would say pair his Arsenal/Red Arrow with Oliver for a bit and then spin him off in his own series or a team book of some sort. It'd be cool to see him fly with Oliver for a little while though. Hasn't been since the Golden Age where we saw these two together on a consistent basis. When it comes to Speedy, revert Roy back to that, or bring back Mia Deardin who hasn't been used in 4 years, or have Emiko be Speedy. I just feel that, like Batman needs Robin, Green Arrow needs his Speedy.
