Once Upon A Time In Texas - S4-E8
Continuity mistake: While talking to Claire outside the diner, Noah comments that he's looking forward to seeing her at the Homecoming game. But in season 1, Noah knew Sylar was going to try and kill Claire at Homecoming and had forbidden her from going.
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.
