The Grounders received the execution they were calling for, but the Spacewalker was not killed quite to their specifications. Unfortunately for the Sky People, some Grounders will believe that Finn did not pay nearly enough for his crimes.

"Yes, he is dead like they wanted but it was quick and not true to the Grounder tradition of punishment," explained Eliza Taylor (Clarke), according to E! Online. "The people don't feel like justice has been brought to their village. I think it's going to make the truce a little bit harder to carry out."

Luckily, the two factions will soon realize that Mount Weather is the true menace of the post-apocalyptic landscape.

"The second half of the season is really going to focus on the Grounder/Ark alliance or the potential of that and how hard it is to make peace after so much blood has been spilled on both sides," Taylor teased. "What we're going to try to focus on is how both sides are realizing they have this common enemy in Mount Weather and hopefully teaming up to fight the good fight against them together."
