It is safe when it's stopped airing on national television. This thread was posted while the olympics were still being aired. After it's been aired, it's up to the people tivo-ing it to watch where they read, but before then, I consider it a very very inconsiderate thing to do. How would you like it if, during the day, before your favorite show's season finale airs where you live, I posted a big old spoiler of the ending with no warning - here on the disboards. I suspect you'd be angry too. Why? Because it hasn't aired where you live yet!
All I'm saying is wait till the olympic coverage is over in the different time zones before you (general) start posting spoiler threads with no warning.
Not trying to be ugly. I'm sure the OP has learned her lesson
