[There's a long silence. The Doctor basically has him pegged right there.]

When do you see me as a villain?

I was underestimated more when... I looked different. Treated as a child, as everybody's little brother. But even then, even though I tried to be a model inmate, I was regarded with more suspicion than the others.

What I'm trying to say is... Even when I'm underestimated, people still assume the worst of me. If they're going to do it to me regardless, why should I let them underestimate me? Why not go all out and be the 'supervillain' they all think I am?
