Some things that occurred to me that I'd like to see in RHATO.
Keeping Secret Identities Secret. I've mentioned this quite a bit in my reviews but it bothers me how causal Jason has been about revealing his real name and showing his face. It's already been shown that--at least in Gotham--he's recognized. DC only seemed to realize this could be a problem when they had the art changed during the DOTF tie in to have a previously maskless Jason wear a domino mask. Everyone in Gotham should know who Jason Todd is and how he's connected to Bruce Wayne. Plus the fact he died. Not that much time has passed.
Red Hoods' past (UTH) and Rent-A-Bat. I suspect Lobdell will mention both as he's the only writer to prove he's read UTH since the relaunch started and built up the latter. This makes him seem far more likely to successfully infiltrate the underworld than any other bat as these stories seperate him from the others. To an outsider it'd look like he's only in it for himself and makes it easier to shrug off his work relationship with the bats.
The Way of the Warrior. I feel like it's likely that the All Caste will be mentioned I'm just not sure how much (if at all) it will connect to Artemis coming from warriors like the Amazons. I'd like to see the Amazons have some past with Ducra. I could see Artemis not taking any the gimmicky super villains or even the heroes seriously because of their style of combat. Not all forms are close combat after all. Maybe she thinks Jason isn't much better because of the guns, at least until she saw he could actually fight hand to hand.
Running into the Ex and an Old Friend. Remember who else lives in Gotham? Jasons' ex Isabel and his friend Gabby. That could make for some awkwardness as he tries to stick to his undercover mission.
Bizzaro Equals More Open Jason ? Lobdell already said Jason would go soft around Bizarro but it's fascinating to think what that entails. At first I thought it would be amusing if Jason is back to his default defensive mode of sarcasm which Bizzaro takes for honesty. Which would be a twist on the Bizzaro talk or at least the reason for it. Anyway if he's gentler with Bizzaro this does bring back more of his nurturing side. The kid that used to take care of his mom and instantly empathized with victims. If Bizzaro is more child like (depending on what the take is) Jasons' defenses could be down in a way not even Roy could achieve.
Past with Black Mask. It's odd that this take of Black Mask is being used. Since the duffel bag was mentioned in Red Hood/Arsenal I think their run in UTH is still canon. Granted much of the extra bits aren't but that part is important. Black Mask was in charge of Gotham before Jason got in his way and made a fool out of him. That means BM isn't going to be thrilled to see Red Hood again and might have more extreme measures against him.
Underpowered but Still not Normal. Artemis and Bizarro both are going to be more super than him. Do they think this means he's the "fragile" one? Jason has also alluded to not feeling like he's a normal person or even knowing how to have a normal life. Will this affect him any worse now that he's isolated from the family?
The "Dark Trinity" Bond ? An interview revealed that Artemis thinks Bizarro is an abomination which makes Jason more sympathetic towards him. What will Bizarro think of her ? What does Artemis think of Jason? What does Jason think of her? I'd guess that his defenses will be up and he doesn't want her to know he died much less his connection to the bats.
Tim Still Believes in Jason. Okay I don't know what is going on with this undercover mission. If Jason is doing it himself, because Bruce asked or if the family knows. If it's one of the first two then I want Tim to suspect something. They built up their bond and it'd be a shame to mess it up.
