Day 5: 5:00 PM - 6:00 PM - S5-E11
Plot hole: This is the first time we see the contact between the boyfriend of Lynn McGill's sister and the terrorists regarding Lynn's keycard. There is no reason they would know each other. (00:06:10 - 00:06:50)
Day 5: 5:00 PM - 6:00 PM - S5-E11
Continuity mistake: When Agent Aaron Pierce steps out of the helicopter, the right half of his face is severely wounded, with lots of blood and a bandage on it. 12 minutes later, when he is back in the Presidential house, he's talking with Miss. Logan and his face is completely clean, with not a single scratch or sign of wounds on his right half of the face. (00:12:55 - 00:25:00)
Chosen answer: Nobody knew, not even the writers, until at least halfway through the season when they were writing the end. They wanted to keep all options open.
