 So it is not sufficient to hold a syntactically identified mental token constant in deciding which worlds to include in the diagonal proposition. We must somehow consider worlds in which the token carries the same meaning it carries in the actual world. However, if we consider only worlds in which the token has the broad meaning that water is wet, the diagonal proposition will be too constrained to play the role of narrow content: it will be false, not true, in a world centered on Twin Oscar.
