Hermione Granger and the Trapdoor Escape

When Harry faints after battling Quirrell in the first Harry Potter book, who rescues him? Hermione and Ron are supposed to wake up, fly through the trapdoor, send an owl to Dumbledore and all should be well. But this story is where somethings don't go according to plan and Hermione and Ron manage to help each other to find Harry a way back through the trapdoor and to the safety of Madame Pomfrey's Hospital Wing. Basically, it's my take on the untold part of the story.
