And upon hearing every single thing those ponies said, she instantly transported them to the dungeon.

If you really need a reason for that scene they probably thought she was either a unicorn with fake wings, a pegasus with a fake horn, or an imponynator.
 
It’s NYC, there’s a lot of weirdos. I was there this summer and there was some guy walking down the street dressed in a Puss in Boots fursuit.

This is what happen when you stop believing in God, they stop showing respect.  
God belongs to a rare 4th race, rules the country and walks among us?  
Pfffff, it’s all made up by mirrors and smoke. I bet those wings are fake.

Did she know where it was?

Seriously, Twilight forgets she can teleport all the time.

The ponies are probably one of the most apathetic lot ever. Atleast till they need their butts saved.

Personally, I’m glad that Twilight didn’t attempt to pull rank.

Since some say that that guy is “4Chan the Pony”, it seems only right that he’d directly refuse to help “Princess” Twilight.

Nobody respects princesses.
 
Without their regalia.

This is New York. Nobody’s going to let you cut in line because of your social status.
