Jonathan Stewart (Earth-43121)

"I've watched good men lay down their lives so that I could survive to complete a mission. Things were different back then. I let it happen because I thought it was for the greater good, I thought there was nothing I could do to save them. I'm all for teamwork, but the second someone suggests sacrificing themselves for me or anyone else, that's where I draw the line. There's always a better way."
