So there's this usage of what seems to be the present subjunctive that I haven't been able to find references on:
A: "He said he was going to kill you."
B: "What? He kill me? Fat chance!"
B: "What? Him kill me? Fat chance!"
Now, I was under the impression that the subjunctive no longer appears in contemporary English outside of idiom and specific subordinate constructions. But here, kill appears in the main clause and seems to be a free use of the subjunctive (entertaining a hypothetical future action). I also can't imagine the present indicative being used instead, unless one is asking a declarative question about a future progression of events.
Does this usage have a name? Any references would be much appreciated.
