Today is the final day of my contest, I'm working on final revisions and stuff, and then later tonight I'll work on my next IC post. I wanted to wait for Role Model, but since it might still be a while, I don't want to risk holding up the group and others losing interest. The part of the story centering around the park will probably last two or three post cycles, and then we can probably timeskip to the next morning when they begin to really notice the changes. They'll wake up to find a huge SHIELD presence in the city and emergency rooms struggling to handle the influx of patients. The media labels it a terrorist attack and biological warfare, while the evil scientists who engineered the event begin learning that the interns were spying on them. 

Kindred, one idea I have for David's first transformation into the Hulk is during their first major battle with a team of villains -- one of the baddies seemingly kills Caty, and David loses his shit like Goku going Super Saiyan for the first time and just explodes in all his green fury. Then she can pop back out and try to convince him she's fine and calm him back down. What do you think? 

One change I am going to add to this version of the Hulk -- he does have a green aura like Broly when he's transforming. This is a result of his skin absorbing and converting particles in the air around him to add to his body mass to facilitate the massive growth. It's sort of a fusion process that releases a lot of energy, and then once he's returning to normal, all that excess mass is purged in the form of steam, like the Titans from AoT in a way.
