Q, R, S, T, U, V, X = ]Q Team[ < 10...
Gooda guess as any, eh?
Actually a VERY excellent guess, Darby.
X doesn't have to be THE "head Q guy", maybe just A Q guy that likes Thundercats. Little "inside NSA humor" like Q says.
And I can see them having code names like T, U, V, etc.
Better than Mr Pink, Mr White, Mr Blue. That's been done.
