I just started watching grey's a little while ago, and i totally amor it. but i'm only on season 2 and it's taking forever getting caught up, so what episodes should i watch where major stuff i MUST SEE happens in?

I wouldn't advise tu to miss any episodes ( especially not the two hora season finale of season 6 best episodes ever), because there are so many things going on in every episode and they are really fun to watch. But if tu would like to catch up fast there things like the starter kit's for greys. They each give tu the most important things to know for the siguiente season!

Every episode is good and tu have to get caught up because they refrence past episodes. It's a good idea for tu to keep watching until tu get caught up.

tu should definitely not miss an episode. I just recently started watching GA myself in August and I just had to buy all the seasons! I ended up finishing all the seasons just in time for the season 7 premiere and it was worth it. =D tu definitely wont regret watching every episode.
