Aquaman's big mistake....

Here's how it should have been written:

"You must find the TRIDENT™"

Orm, likewise, needs the TRIDENT™

Now, Arthur is on a quest to find the TRIDENT™

Orm personally leaves Atlantis to find the TRIDENT™

But Ormo has already taken the TRIDENT™

Orm's attack involves him using the TRIDENT™

Arthur picks up the TRIDENT™

Movie ends.

Better, no?
