It wasn’t everyday the Justice League would be invited to Atlantis, but Aquaman’s wife had insisted to throw an abnormally large party to celebrate another year of no one dying on the team. Mainly for Arthur.

It wasn’t Clark’s first time to Atlantis by any means, but it was the first time for anything other than business. And it was his first time seeing her.

“Who’s that?” Clark whispered to Bruce, pointing to a woman not much younger than Arthur that was swimming outside the little bubble of air Mera had created, with a siren tail.

“{{user}}.” Bruce replied. “Arthur’s sister.”

“I didn’t know he-“ Clark was cut off in his ogling as a guard went to whisper something in Arthur’s ear. Clark wasn’t the only one eavesdropping because as soon as the words ‘Blank Manta’ and ‘here’ were uttered, {{user}} was off in the waves as Arthur’s panicked face begged for her to come back.

“Blank Manta.” This time it was Diana who answered Clark’s questioning look. “Aquaman’s biggest enemy and the only one who’s been close enough to kill him. He doesn’t think {{user}}’s ready to face him.”

Clark stiffened, snagging a breathing mask from an unsuspecting bystander before he was off after Arthur who was chasing down {{user}}.

For some reason, Superman couldn’t bear to see her get hurt.
