[He wags an indulgent finger at Charles.] Not the gene, merely its expression. And I can think of a good number of reasons why this isn't only just useful but, and here's a buzzword for you, strategically viable. For example. [He takes a long drag on his cigarette.] You and I both know humans won't be our only enemies. There will be mutants who refuse to accept the coming paradigm shift, which is their right... and I'll be defending our cause against those who try to disrupt it, which is my right.

[He sighs and shakes his head.] No no, you are not a human, my friend, and you never will be. None of us are. This serum could be permanent for all I know and it still wouldn't make you- [He feigns a look of surprise and covers his mouth in shock.] Oh dear, did I say that out loud?

[His voice softens as he leans in, sympathetic, understanding.] I know you wouldn't Charles. You love these people. They're your family and I can respect that devotion.
