"There she is" Khan said rising from his seat on the USS Reliant
He see's the USS Enterprise appear on the Viewscreen
"Khan there hailing us"
"Let them see us" Khan said
"Im captain James T Kirk of the USS Enterprise to USS Reliant are you in need of assistance..... Who are you?" Kirk said
"Captain I thought you were a admiral?" Khan said since hearing Chekov speak on the Bontany bay a few days go. He was also confused as this Kirk looked as young as he did all those years ago when he had tried to kill him on the USS Enterprise.
"You have me at a disadvantage state who you are and where is the captain of the reliant?" Kirk said confused at how this old man seemed to know him
"I my dear "Captain " is Khan noonien Singh but I'm tired of this ignorance you seem to have Kirk from hells heart I stab at thee
Khan cut the communication and gave the order to fire all weapons
(This is the original Khan he has the USS Reliant but no Genesis weapon board. This is New Kirk on his Enterprise with his crew. They have not met Khan so have no idea who he is or his capabilities)
