A Love between a Norse Goddess and A Human
"Well, when SteeL was first assigned a mission from S.H.I.E.L.D., she was new at being fully good. She got pissed off by Hill, and then she went out of control. She destroyed the Helicarrier."
"Yeah, so he learned to not upset her. He still respects Cassie."
"She's my sister, Cassie Stark. She's my younger sister, but not my youngest. She's the human form of SteeL. She's the one I'm trying get back, from that Goddess, SteeL."
"Oh, I see."
"Why don't you go train?"
"I swear he's going to make a move on Cassie, and I'm going to kill him."
"She'll be fine. If she can handle, the other guy, she can handle him."
