SPOILERS! Season 2 Episode 15
Maybe future episodes will make this make sense, I don't know. You mean to tell me the commander is going to let 250 people get blown up by a missile and be satisfied with getting a few people back from the Mountain people?
She went to the Mountain to wipe them out so her people could be safe forever from the Mountain people. She wanted revenge for what they had did to her people. She was furious that they had killed thousands and turned so many into monsters. Her own words.
The whole storyline in beyond fricking ridiculous!
