Other: There are several shots of monitors which show the time and date. Right before the coffee shop explodes, the date is said to be Nov. 16, 2027, but at the farm house when Luke is playing the newscast, the date is April 2, 2027. Furthermore, when the alarm sounds at Jasper's house, the date is now Dec. 6, 2027.
Continuity: As Theo is sitting down at his desk, the camera comes up from behind the woman across from him, who has small knick knacks and figurines covering her desk. The shot zooms in on Theo and then switches to the crying woman. When the shot changes, notice the "fat-baby" figurine suddenly switches with two-smaller animal figurines. It's hard to tell what they are, but it's easy to see they've been switched with the baby.
