so, you’ve been replying to a few of my things, and I’ve responded in the notes of the other post. You seem to not like Echo, but i hope you’ll read this. First, Echo and Bellamy didn’t know Murphy was shot. They were outside of the rover when Murphy started shooting the gatlin gun, then after Bellamy and Echo took out the canons, Madi yelled “charge” and we can assume Bellamy and Echo just followed Madi without checking up on Emori and Murphy. It is then clarified that Bellamy and Echo didn’t know Murphy was hurt when Harper told Bellamy that Murphy was shot.  

You better believe that if Bellamy and Echo knew Murphy, Emori, and Monty were struggling to get to the ship... they would not have just been standing outside the transport ship waiting for them. Second, she didn’t know Bellamy wasn’t getting inside the ship.. he told them all to go and that he was right behind them. And she didn’t have access to a radio to overhear Clarke telling Raven that Bellamy was outside the ship.
