Sam's last mission

I can't believe Sam died surrounded by destruction. I know my sister. She would never destroy a base...well...baselessly. When we were kids, I was always the one breaking and rebuilding things. She wouldn't even go into a bake sale without a plan-- for classic oatmeal cookies, no less. So serious. She wouldn't have anything to do with my molecularly transformed caramel pretzel lumps. She must have been upset. Or rushed. Or both. I can't believe for a minute she caused that cave to collapse by "negligence," as they called it. That's not Sam. She had a plan. It just went wrong.
