'H2.0' part three! Aquaman and Mera learn that the 'strange water' they've been sent to investigate is in fact a gateway to an alien world that's the source of Arthur's recent troubles! And tensions flare between Aquaman and his less-than-heroic teammates over whether to make contact with this new world or destroy it!
