@bobevanz - The fact that there was no Luis story is incredibly disappointing.

@ElvenKingSlayer - as far as I can tell, they never addressed either of those. So yes, these are still unanswered questions. Especially since we never got an explanation for the powers or anything about the layout of the quantum realm to begin with. Remember, sending a signal was enough for her to freak out. Sending Scott there? That has to be worse.

@Origame - eh, not necessarily. We don't know the layout but we do know there are layers to it. They establish that tardigrades, for example are in the Quantum Realm because Scott is told to avoid them when getting Quantum energy, as well as Time Vortexes. We saw when Hank was going deeper and deeper into the quantum realm he was getting smaller and smaller to go further and further in. For lack of a better analogy, if where Kang is can live on the surface of a penny, where the tardigrades are can live on the surface of a bowling ball. Again, that's an extreme over simplification.

So yes none of this is STATED because it would become a boring exposition dump of science mumbo jumbo, but I think it can be explain away as Scott isn't even perceivable to Kang, much like the real world isn't, when he's that "high up" in the Quantum Realm.

Or, another way of looking at it, think of the Quantum Realm as space, right? Cassie sending out a signal into the quantum realm is like sending a signal out in to space, if that signal is found it's origins can be traced and located. On the other hand sending Scott to the quivalent of us sending someone to the moon, another civilixation light years away would have no idea it's happening.

@SATW42 - but we need the bare minimum to understand why Kang doesn't know them. Your explanation is fine enough, he's not on the same level. All that was needed was for hank to go "why didn't you say something when we sent Scott down here" then Janet says "there are different levels of the quantum realm based on size, I chose a different level for scott". Not much science there to get.

@Origame - eh I take it back, he'd know about levels but doesn't know Kang is down there, so yeah, he could've asked.
