Earth is a dangerous place.

The 100 Season 1 Episode 3 was titled "Earth Kills," but it could just have easily have been called "People Kill." At this point, I'm not sure which is more dangerous on Earth: the environment, the Grounders or the 100. 

Regardless, the kids dropped on Earth have a better chance at long term survival right now than they had on the Ark. Up there, they were just counting down the days until they were floated.

On Earth, two factions were forming with Bellamy and Clarke as the disparate leaders. Bellamy accused Clarke of being weak and not being able to make the difficult decisions when she wanted to help save Jasper instead of ending his misery.

Bellamy started out being about freedom, but quickly became about control and power, while she's motivated by community. Bellamy has good reasons for hating those in power on the Ark, but so does she. They both lost family members due to the strict rules and punishments.

When Bellamy was faced with ending Atom's pain, he couldn't do it. Clarke though didn't hesitate. She calmed Atom by humming and peacefully stuck a knife in his neck. If she didn't believe she could save Jasper, she would have done the same to him.

The look that Bellamy gave Clarke in that moment was one of respect and honor. It's unclear whether the rift between the two leaders will close now, but Bellamy did tell his people to give Clarke whatever she needed when they returned to base camp.

It's not going to be all sunshine now, but if Bellamy and Clarke can cooperate more than they fight it will be better for the group as a whole. Though, Bellamy's control over his people seems to be breaking a little. Even Bellamy's sister, Octavia, is spending most of her time with Clarke and her friends.

The poison cloud claimed one person's life, but more would have died if the Grounders hadn't sent a warning. Was it meant for other Grounders? Or, were they warning the newly arrived humans? Either way, that warning was life saving. Perhaps the Grounders aren't all bad. They did save Jasper after spearing him. 

"I guess we're going to have to get used to people dying down here," said Octavia. While that's certainly true, it was something they should have been used to from the Ark. Her mother, Clarke's father, and Charlotte's parents were just a few of the people floated on the Ark.

It was uncomfortable to see Clarke treat Wells with such disdain, especially after he purposefully got himself arrested to get on the drop ship. He loves her and wanted to help protect her. He was the best friend he could be for her by taking the blame for Clarke's mother. He didn't want her to lose both her mother and father.

At least, they made up before Wells was killed, even if his death will be even more difficult for her. It wasn't much of a surprise that Wells died given all he's been through since they landed. What was a big shocker was that Charlotte killed him.

The young girl took Bellamy's words to heart and slayed her demons. The Chancellor killed her parents and Wells paid with his life for his father's actions and the rules of the Ark.

It would have been horrible if Wells was killed by Bellamy and his posse for being the Chancellor's son, but it was heart crushing to see Charlotte kill him. It's sure to cause conflict within the group and a further divide between Bellamy and Clarke.

Jasper may have been saved, but both Atom and Wells were killed. Plus, Trina and Pascal are still missing. The group continues to shrink. Instead of rehashing the same leadership battles, the story progressed in an authentic manner. The two groups headed out to hunt for food and medicine.

In three episodes, the characters have shown that they are multi-layered and not just stereotypes.Throughout the episode, I was pleasantly surprised by the developing depth of character. Bellamy originally was shown as an unlikable dictator wannabe, but he's evolved into a m​ore sympathetic guy.

The 100 has far exceeded my expectations over these first three episodes. At the end of each hour, I'm not ready to let them go for another week. The life threatening situations create suspense and anyone can die at any time. That's something special and unique for a television show.

What is the greatest threat on Earth?
