well she said "we lost 2 brothers.. I don't want to lose another.." I just assumed that tank died.. but it is kind of weak that they just went off and killed him without telling us.. they are on the ship in the beginning and I am like "where is tank?" I didn't like that too much.
Oh and reply to someones star wars comment.. when they are meeting with the concil (wow I can't spell) I was like "this reminds me of star wars." creepy...
