Bloopers[]
In the piecing/tattoo shop Claire works in, she pierces a girls ear using a gun. In an actually piercing shop, they would use a needle. Guns are only used in jewelry stores to pierce. Also, the girl appears to receive a 14-gauge ring. A gun would pierce a much smaller hole, used for a stud, not a standard ring. Also, it's highly unlikely that the whole process would only cost $10.
Mikhail/Locke[]
Is no one else bothered by the fact that Mikhail clearly recognized Locke, was cutoff before he could say from where, and then was mercilessly pushed to his certain death by Locke (the first time Locke ever attempts murder)?
