Iris gives out to Sherloque for not telling anyone about his investigating of Nora. Except he did in "Seeing Red", even asking her a few questions about Nora's behavior, the only difference now is that he has some evidence to back up those suspicions and has figured out what she was hiding.
It's noted about Godspeed that no other speedster has white lightning, even though Savitar's lightning was white whenever he wore his suit.

An intelligent CSI like Lia would know the way to open a drum with a lock-ring closure is to loosen the bolt on the lid ring. Instead, she wastes valuable time trying to pry the lid off with a bung wrench, which is useless for either approach, as it is designed to open an entirely different type of drum.
When Nora's in the Flash Museum investigating Speedsters, she says that Godspeed's lightning turned blue, like Zoom's. However, Godspeed's lightning actually turned white, rather than blue.
