Japanese to English Tech/Engineering Games / Video Games / Gaming / Casino

ALERT: This is a stupid question, and it involves an elementary point of vocabulary, but it's causing a problem, so I am bothering everyone here with a question below their pay grade.

In a fantasy video game, the hero is traveling with two companions. One is an android; the other is a robot. A townsperson sees them and remarks:

「そちらのロボットとアンドロイドのおじょうさまがたにはいちどおあいしましたね」

The speaker has not met the hero before, only the android and the robot. There is nothing more to this conversation. Does the use of がた in the above sentence indicate:

1) The speaker believes that the robot and android are both female.
2) The speaker is indicating only that he believes the android is female. He is indicating nothing about the robot.
3) It is unclear.

I've asked this question elsewhere, but I've gotten conflicting information as to whether the がた is meant to indicate plurality or only respect. I'm hoping a native speaker here can give an opinion.

Thank you for your patience.
