The only way we know this is from the later scene where Orm and Mera are all happy with Aquaman after everything is over. But that whole "at last an heir", "oh, nobody's happier than me" if you know that Orm is Ocean Master (as he has been in comics since the character's creation) sure seems likely as a primary goal for the Light -- interfering with Mera and her child gives them the chance for one of their members to rule Atlantis -- another country under their control. When we last see Orm and Mera during the battle, Orm will be alone with Mera "under his protection" once Garth takes off -- we don't know what happened between that and the end scene.
