I'm trying to be optimistic. I think there's a reason both The Doctor and Jenny have yet to really make an appearance. I think it would really suck to have either of them show up and fix everything with their magic uber powers from a storytelling viewpoint, but at least things would be good again.
Viruses do not work that way is exactly what I thought when the whole, oh, the virus doesn't die in Apollo because he's a metahuman with more endurance, oh, and also, heat makes the virus thrive so going to the sun doesn't help! Really? The sun can't burn that thing up? The frickin' sun!
But, honestly, I'll let it go if they just don't kill him. Apollo is my favorite and he has to live to see a day when come comic writer can actually do something with him besides being Midnighter's reason to be sad/pissed off. Please,please,please!
