If there is a group of deagentive reflexive constructions, where (a) the agent can be expressed, (b) there is no subject, and (c) there is a direct object, then there will be (or must have been earlier) two other groups of deagentive reflexive constructions; one group, where (a) the agent cannot be expressed (b) there is a subject, (c) there is no direct object; and the other, where (a) the agent cannot be expressed (b) there is no subject, (c) there is no direct object.

DEAGENTIVE RC is a type of RC, with the agent identical with the agent-subject of non-reflexive construction, but not expressed by a subject RC.
