The tsuba box jumps from the table to under Dickenson's arm as he talks with Pete and Myka about Artie.
When the man comes to release Artie he unlocks one of the handcuffs but in the next scene Artie is removing both handcuffs.
When Myka is looking at the photo and paining of the sword she put two photos next to each other but in the next scene they are above each other.
When Pete and Myka are being driven out of Washington DC, the SUV they are in stops at a light at Matheson Blvd E. This is at the corner of Orbiter Dr. and Matheson Blvd in Mississauga, Ontario.
