I love this moment but I have huge problems with it at the same time. Santana may be a bully and she deserves some sort of revenge brought upon her but Finn Hudson is an extremely flawed character that thrives on hypocrisy and outing ANYONE is not okay in a school hallway when there is plenty of kids going around and over hearing that conversation. It pisses me off that this issue was not fully explored in the series. All that happened was a slap (which was amazing btw) and then Finn blackmailing Sanatan into coming back to Glee club or she'd be suspended. Also, the fact that Kurt is shown there sitting quietly just makes me remember Finn calling him a fag and that episode when Kurt and Sam were supposed to do a duet together but Finn told Sam not to because of Kurt's sexuality.

Yeah I checked earlier, and thought that if no one really knew the location, then the people that said they did, were just sort of making it up. 

LOL. I know it's ridiculous. I'm hoping he doesn't know the story of Les mis, rather than him just being annoying. :P
