Employing the reflexive tenses

"I AM HE" shouts Agent Three to the pummeling rain.

"BUT HE IS NOT ME" he answers.

"I AM YOU"

"I AM MYSELF" he crows.

Under an awning, smoking a cigarette, he speaks calmly.

"I have a reflexive relationship with my self-identical antecedent."

"In the reflexive verb tense, a semantic agent and patient are the same."

"The reflexive closure of a binary relation R on a set S is the smallest relation R′ such that R′ is a superset of R and R′ is reflexive on S."

"The reflexive reduction of a binary relation R on a set S is the smallest relation R′ such that R′ shares the same reflexive closure as R."

"I do not know who I am."

"I am myself."

"I know myself."

"I am here again."

"Of course."
