(Volume Two: Generations) Four Months Later... - S2-E1
Factual error: In the scene where Hiro is in ancient Japan posing as Takezo Kensei to rescue the girl, what looks like a Gatorade bottle can be seen in the grass as they ride away. (00:18:45)
Factual error: In Season 2, Episode 3, Peter and the Irish family rob the bookmakers and the security guards shoot at them. In Ireland, even the police don't carry weapons. Let alone security guards.
Factual error: When Nathan goes to Cork to find his brother, he gets out of a black cab with a yellow license plate, both of which are characteristic of ENGLISH taxis, not Irish ones.
Chosen answer: Hiro's powers are still quite unreliable, and a locked closet door isn't a huge obstacle. Since Hiro knows he needs to rescue Ando, it's probably safer to try and bash the door down than risk teleporting to the wrong place or time.
