One of them is not human

"There was a little confusion abducting one of your mates." Z7 informs you "One of your selected mates was a marine biologist who was Swimming with a dolphin at the time the photo had been taken and when it came to abducting them."

You remember seeing her photo, you assumed that she had been swimming naked with a dolphin for some kind animal themed nude calendar or some research project. What was the problem with that?

Z7 continues "The scan to find your selected mate found two galactically sentient specimens both of which matched someone in the sample photo and were both females. The zeron in charge of the abduction could not tell which one you had selected and **** the wrong one. By the time the mix up was discovered she had already been fitted with a translator chip and briefed on the existence of the galactic council. She will not count towards your chosen human mates. As she is a different galactic sentient species and was already briefed she will become the council representative for all dolphin species as it would be impractical to choose one of each species. As like the Felionester and mice you will have an attached habitat. Your first contact plans laid out in the last meeting will have to be altered and agreed on by the Dolphin ambassador before they can be enacted. Your third selected mate will be properly acquired and will arrive after the next galactic meeting in a week's time. The other two and new ambassador are waiting for you."
