1X02 Earth Skills (Bellamy)

It happens so fast - Clarke is rushing towards the tree, and then she's not. You act on instinct, darting forward to grab her wrist before she falls to a messy death. You wish you'd been just a second too late, because now you have to make a choice.

You could eliminate your only real threat right now, and she knows it. Her wide eyes are locked on yours, and she knows you could let her die. A dozen wickedly sharp points line the trap. Maybe it would be quick.

You wait too long, and wonder if you're sorry you hesitated.
