But the bathroom containing the entrance to and exit from the Chamber of Secrets is on the *second* floor, which, as I said, seems like an odd place for students and staff to congregate. That's the bathroom in which Moaning Myrtle died. (I know it's not a bathroom in the sense that people bathe in there, but "toilet" is specifically used to designate the, erm, porcelain fixture that Myrtle dives into when she wants to sulk in the U-bend/S-bend depending on the book.)

It doesn't really matter how Moaning Myrtle gets around. We see her in the lake, in the Prefects bathroom, and in the boys' bathroom where Draco is crying in HBP. It's the bathroom she died in that matters because that's the one that contains the sink with the tap that doesn't work.

But my concern is the Basilisk. Yes, he moves through the pipes like Moaning Myrtle (though she can also move through walls like any other ghost), but unlike Myrtle, the Basilisk is solid, and he's also huge, much too huge to fit through the tiny hole in a toilet. How did he get to those other floors? I'm surprised that Ginny, who was being used to control him by Tom Riddle, could get the Basilisk out of and back into the entrance to the CoS without being seen, much less getting it onto some other floor. I won't even ask whether Possessed!Ginny was just waiting for Muggle-borns to show up.

Anyway, the more I think about CoS, the less plausible I find the plot.
