Hal's admissions interview (p. 9)
‘By whomsoever’s calling—N.A.A.U.P., ill-willed Pac 10 programs, O.N.A.N.C.A.A.—’ The essays are old ones, yes, but they are mine; de moi. […] If I’d done you one from the last year, it would look to you like some sort of infant’s random stabs on a keyboard, and to you, who use whomsoever as a subject.
Context
A Dean is mid-sentence when Hal's silent rebuttal cuts in. The clincher is pure Avril-trained contempt: the man questioning Hal's authorship can't decline whomsoever. Grammar as the last scorekeeping available to someone who can no longer speak — and the "infant's random stabs" admission quietly concedes the prodigy's collapse.
