After Alibaba reunites with his friends and tells his story.
Sinbad: Mm. This girl hides her penis quite well.
Aladdin: Wait what!?
Morigiane: How do you know its type?
Sinbad: Ah that, I just noticed a painting representing her at the royal palace.
Alibaba: Yes, so what!?
Sinbad: Well, it seems that you are wanted by your older brother the king.
Alibaba blinked several times and yelled: And what does this idiot want from me?
Sinbad shrugged under Alibaba's suspicious gaze.
His older brother had simply shown Sinbad the portrait of Alibaba if he saw his sister.

It was only later when we confronted the Magi of the Ko Empire who got the answer.
See you in the next chapter for the reveal.
