According to many sites I've recently looked at the Lex corp , Wayne tech, and Supergirl easter eggs weren't the only to be shown in the film, apparently the oil rig that Clark works for as one of his jobs throughout the film has caused problems for Aquaman. The CEO of The Merrevale oil rig Jordan Wylie actually had run-ins with Aquaman due to drilling in Atlantis territory and environmental destruction. All of this possibly suggesting that Aquaman caused the oil rig to catch on fire and followed with The 2 humpback whales that are said to have been sent to check on Clark.
Does this mean Aquaman will be in Justice League, He's the first member to distantly meet Clark or be aware of him, and a possible Aquaman film is being thought of like David S Goyer suggest?
Thought this would be fun to share :)
