If you have not watched this episode yet, or are not this far into the series, you should NOT read the rest of this post, as it most definitely contains spoilers.

So, the episode starts off with Hiro and Claire in the past, 16 years ago, overseeing the point where Claire is given to her adoptive father, Noah Bennet. Hiro witnesses his mother’s power to heal, and gets her to restore his memory, as well as give him the catalyst.

While Hiro is off changing the past, Claire goes and changes her own diaper when she acts like a neighbor and helps her mother with the new baby, which is her, in the past. Yeah, I know, all the time traveling can get a little confusing sometimes.

So now that Hiro is the catalyst, and Claire is not, who knows how their lives changed, if at all? We’ll never know because the show decided to make a big decision in the past, but have no consequence in the preset.

Claire and Hiro meet back up but Arthur Petrelli shows up. I didn’t even know he had time traveling power. He sent Claire back to the present, then he took Hiro’s powers, as well as the catalyst, and threw Hiro off the building.

Ando, Matt, and Daphne find Isaac Mendez’s old sketchbook, which shows the future, but in this case, it is showing the past, as it shows Hiro hanging from the building, from a flag pole. Yeah, like I said, all the time traveling can get confusing. So now Hiro is stuck in the past, with no powers, hanging on for his life.

Peter and the Haitian head to Pinehearst to kill Arthur Petrelli, Peter and Nathan’s father. Arthur senses Peter coming and confronts him. Arthur releases his powers are gone and the Haitian walks out. Peter aims the gun at Arthur, he battles himself to pull the trigger as Arthur tries to persuade him to join his cause. The Haitian can barely hold back Arthur’s powers, Peter finally pulls the trigger, the bullet stops in mid air. The camera pans over and it’s Sylar! Sylar stopped the bullet, talked a little, then said, “Peter, you’re not a killer.” Sylar then used his powers to make the bullet shoot right through Arthur.

So, some pretty big things happened in this episode. Hiro is stuck in the past, without his powers, Peter almost killed his father, but Sylar took the kill instead, and the catalyst is gone, as far as we know. With Arthur dead, I’m worried that Hiro and Peter may not get their powers back. I sure hope they do.

Heroes airs on Mondays, at 9PM EST, on NBC. There is only 1 episode left this year, and season 3 will conclude sometime early next year.
