Bellamy refuses to give up on Clarke on "Wanheda: Part Two"
Bellamy's desperation and his devotion to Clarke was clear as day all throughout this episode. First, he sneaks off from the group and walks through an army of grounders to get to her. Then, he continues to limp after her after being stabbed in the leg. And let's not forget the outburst where he screamed he couldn't lose Clarke. If that's not love I don't know what is.

Clarke's ability to use her head in impossible situations alongside Bellamy's desire to do the right thing has always made for an amazing leadership dynamic between them.

Bellamy replies with, "I've got you for that," and I'm pretty sure that's when my soul left my body.

Bellamy going into overprotective mode when it comes to Clarke will never get old. When Clarke's in danger it's almost like his rationality goes out the window.
