Agents of S.H.I.E.L.D., Season 2

Karla Faye Gideon:
Maybe it would make more sense just to forget about S.H.I.E.L.D. M-Move on. I mean, haven't they robbed us of enough?

Calvin:
That's the point. We can't forget. We can't just slink away and let them take from us. From me! They took my little girl. They stole her from me, and they still have her. She isn't safe there. Losing a child, it, it tears you apart! I'm just like you. I wasn't strong. I couldn't protect the people I loved. So I tried to change, improve myself, with chemistry. Results were inconsistent. Some volatility issues. But I keep working on a formula. Always tweaking. We can't stop now. We can't let them make us afraid or make the world afraid of us! They are the criminals, and we're gonna shine a light on that!
