Spoilers for HPMoR (though I guess that’s a given at this point):
c) how does she miss the fact that the map shows two Tom Riddle’s walking down the passage way to the graveyard? That should not be easy to miss.
It says “it was tangled and confused”, but it would still show the name twice, and if she can read the one, it stands to reason she could read the other. Especially since we have precedent from HPMoR of both being in the same room without the map being confused.
