The twist in this episode felt like it was added on in an impromptu manner. The judges' description of the twist was less clear than Krystle and Amie's description of their monster. It felt like the powers-that-be were giving the teacher's pets (Christian and Aaron) a second chance or basically a 2nd golden brick that they didn't deserve. This is the second time that Christian and Aaron should have been in the bottom two. If Christian and Aaron win, I won't be tuning in for season 2 even though I love the show 100% otherwise.
Oh, and in the previous episode, everyone was given 6 hours for the main build and an additional 6 hours for the twist, which seems reasonable. This time, they were given 14 hours for the main build (which is 2 hours longer than the entire previous episode) and only 4 hours for the twist. It really feels like they were tossing Christian and Aaron an unearned bone and giving them just enough time to fix things.
