They reran the Jack Episode 4 promo stating that the next ep will air "next Saturday at 11". ... this means the same promo for ONE episode is now airing for TWO weeks in a row. Wow. Wow.
Also, DeMarco tweeted a few days beforehand about this stunt. So there WAS a way people could find this out in advance, but again, very few people only read the tweet in time, INCLUDING ME!!
