The intended mate - Leeloo, is thirteen years old, so it seems this is a last ditch attempt to get offspring from her. With that in mind, I wonder whether the male that will be sent across will be Kembali.
He's of age where he can be introduced and breed immediately; compared to his younger, inexperienced son, Ketambe. Additionally, I personally think it's unlikely he will receive a breeding recommendation with Delilah again, and so with his nieces recently being born at Hamilton, he ultimately has less value within the region.
