Laura embraces the insanity in this chapter. Caitlin strikes at Verity. Diet Coke explodes. Please read the chapter first so you don't run into spoilers.
Laura's moment to choose what she is arrives. She, however, went with the flow. Laura also started showing her scary side. Caitlin wanted messy; Laura suggested gassing a building. Her suggestion of Mentos and Diet Coke is a real thing. The Diet Coke reacts to the chemical composition in the Mentos, with the dimples is the mint aiding the reaction by providing more surface area. Mythbusters did work out what was needed for the reaction, and did show a spray that went above their building's height.
For someone new, Laura found a way to start taking advantage. She managed to get several items she wanted placed on Caitlin's tab. Laura may not feel like she's fitting in, but only because she isn't really a follower. Part of Laura's issue is with authority. She's been in a culture that is outside the law for the most part, acting as her father's chief chemist for his drug dealing. Caitlin, at least to Laura, is very much an authority figure. The two do have friction in the next arc, and the hints of the problem have been laid down.
For all Caitlin was against a juvenile prank, she leads the girls in a juvenile prank. Notice that Caitlin never came up with the core plan involving the exploding cola. A small test for Laura, to see how resistant she is to anti-Verity work. If the plan works, Caitlin takes the glory. If it fails, Laura gets the disappointment and possibly the punishment. There is some backstory to the Caitlin-Verity rivalry that gets hinted at. Right now, I prefer that readers imaginations fill in what happened.
The arc wraps up with Laura making a decision about who she wants to be. It echoed back on the end of Chapter 6 and let me bring the arc to a conclusion that still left the door open for more later.
