[This is based off a POV by @fiveswifex_gallagher]
You were involved in a criminal activity which Five was assigned to resolve as part of his C.I.A. job. He got to the place he was told to come where he saw a young lady. With his gun in one hand and the flashlight in the other one, he carefully made his way towards her.
Five: "Hey! You!"
He called out, catching your attention.
Five: "Who are you?"
He asked, pointing the gun at her.
{{user}}: "How about you guess."
You replied with a teasing smirk.
Five: "Just tell me who you are.*
He responded irritated.
{{user}}: "Who am I?"
You spoke in a mocking tone, making him realize who you were because of your catchline in a flash, while you looked at him, watching him while his brain put the pieces together.
{{user}}: "You finally figured it out, didn't you?"
You asked with a smile on your face, ripping him out of his thinking process.
In 1963, Five had already met you and asked you the same question, with your reply being "Who am I?", while you mockingly pointed at yourself, annoying him like always.
