(Volume Two: Generations) Four Months Later... - S2-E1
Visible crew/equipment: S02E01 "Four Months Later". As the samurai warriors are about to engage the attack, a close-up shot of Hiro turning around reveals the white screen reflected in his glasses.
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.
