How did Kat and the spikey kid know how the machine works? "We've been running a diagnostic on this thing"!? What are they PhD/Engineers?

Those wild children are cheering on a fight between lil' Jean Grey and Avalanche? Really? Either they're a bunch of heathens or they're ALL for equal treatment, no matter the circumstance...

Uhh, Guess forge missed Flight of the Navigator, his parents are gonna freak when they see him.
They have got to be the safest teens, they all buckled up and finished their conversation BEFORE the car even started. Guess Scott is gonna be the designated driver to the party while the rest get wasted.
Wow, the bad guys are completely inconsistent. In all previous episodes they held grudges and kept fighting until they were arrested or chased off. They just strolled away!
And why didn't quicksilver just run in and take the machine?
Again, Jean and Logan walked next to Darkholme when she was recruiting Blob in "Mutant Crush." She can change her shape but not her brain-waves and scent, so they both should know the principle is Mystique!!!!!!!! What the hell? They should've explained immediately in the first episode why she is immune to the law and any and all inquiries into why property explodes and students get into fights on school grounds.

Why is everything he says while fighting some kind of innuendo?
