"I was the Commander of my people. It's a hard thing to shake." Lexa has grown all too used to passing along the supplemental information that's necessary here: that she led her people not just as a military leader, but as a politician. Commanding means everything that it should mean, as far as she's concerned. She doesn't want there to be any confusion about her approach to things, not anymore.

"Still, how important we are here is up to us. I fight this war because some of my people are here." Even if they deny that status. Murphy certainly does. "But there is still the risk that more might come from my world. Or your world. That is the burden you face now. Do you wish to fight for them, or strike out on a new path?" For her part, Lexa will always be burdened by where she's come from. It's how she maintains her ties to her identity.
