In the beginning of the episode when Duncan looks at the envelope he found at Meg's house, there is a text written on the back saying "Private and Confidential - this means you!", but when he later looks at the same envelope towards the end of the episode, there is no text there to be seen.
When Weevel rips Kelly's shirt, you can see that he ripped all of the buttons off it and it was fully opened. When you get a front shot of Kelly, only a couple of buttons are missing and the bottom few remain buttoned.
When Logan saves Veronica and they come to a stop, she leans over to cry and is very clearly buckled up. The camera switches to Logan and then back to Veronica as she jumps out of the vehicle, without unbuckling her seat belt, though she would not have had time to unbuckle.
When Veronica (Kristen Bell) first walks into Meg's hospital room, the blue sheet is pulled up to her chest, but as she slides the food cart back the sheet is folded back to expose Meg's (Alona Tal) stomach.
When Veronica tells Logan he should move out of Neptune and the camera angle switches back to Logan, a mic is visible next to his right shoulder.
