An Ark flashback reminds us what these characters looked like clean!
There is nothing quite like a song to make you feel nostalgic.
And a good flashback doesnt hurt either.

Tonights tune of choice was Radioactive by Imagine Dragons.
Well, I should say a cover of it.
I was one of the few people who didnt hate that particular part of the pilot.
(Does this mean I have bad taste in music?
To quote my colleagueKatie Minard, Radioactive has becomeThe 100s Chasing Cars.
Were the flashbacks necessary?
No, probably not.
But I loved them anyway.
Ontari immediately chips the Grounders who enter the gates.
Jaha tries to get Kane to take the key, but he resists.
says hes part of the 3 percent of people who arent taking the key.
They take Kane to a room where Abby tries to pretend as if shes not chipped.
She says they interrogated her and want to know where Clark is going.
He believes her until she starts kissing him and pushes him onto the bed.
He realizes then its not her and refuses to help, so they decide to crucify him.
Yes, CRUCIFY HIM.
1.0 DOES NOT F AROUND!
Its painful to watch and even more painful for Kane to endure, but he doesnt break.
He refuses to join them, even when Jaha says he can stop the pain.
Kane would rather be shot.
And he even asks Jaha to shoot him when his former friend grabs a gun.
But instead Jaha trains the gun at Abbys head.
So, naturally, Kane agrees to take the key.
For a nice guy, Kane is getting it pretty easy.
But dont you worry, Indra will confirm he receives his punishment.
Shes found a way to pull her cuffs from a piece of stone.
NEXT: Flashback time!
In between Pike getting his due punishment, were treated to Ark flashbacks.
Remember how he was just a teacher?
He asks about Clarke, but shes in solitary until the ship drops, so she wont receive training.
She paid attention the first time, he says.
), Harper, Octavia, Monroe (!
), and Fox (!!).
They all have major attitude and show zero interest in learning how to make a fire.
He begs Jaha to be sent down to the Earth with them, but the chancellor says no.
He thinks this is the best way to get the kids to learn.
He starts beating up Murphy in an attempt to get the other kids to work together.
Or at least Im guessing that was the lesson?
I just dont know with this guy.
Do you want your revenge, or do you want your people to live?
Pike smiles at Murphy for the assist to which Murphy says, Go float yourself.
Everything I learned I learned on the Ground.
This is anactual gif of my reaction.
The fearsome foursome are making their way to Luna, based on Lincolns map, in the rover.
They get to the water, but where they hope to find a village, they instead find rocks.
While Octavia and Jasper are making green fire, Bellamy and Clarke talk about forgiveness.
Clarke points out that she was trying to get forgiveness for Mount Weather, as well.
Maybe well get that someday, she says.
We need each other, Bellamy.
And then they hug…before being attacked by Grounderscoming up from the sea.
(Just when you think youve seen everything!)
Octavia downs hers without question, and Jasper follows suit.
The four wake up in a rusty shipping container.
Their weapons are gone, but fortunately Clarke still has the chip.
A woman walks in and its Luna.
Clarke gives her the spiel about being the last of her line and how she must take the flame.
Luna says thanks but no thanks and walks out of the container.
They all follow her out and find themselves on an old oil rig in the middle of an ocean.
