From the most recent chapter of my WiP:

They assumed, he supposed, that he was simply cooking them in the Execution Chamber ovens, like any other supervillain.

“Supervillain” refers not to “he,” the one doing the supposing, nor to “they,” who are doing the assuming, but to other people he would have cooked in the execution chamber in the course of normal events. Should “supervillain” be plural here, then, since the “them” he is assumed to be cooking (but is not) is plural? Does this question make any sense? Blah?
