What's going to happen to Adrian Veidt?
After getting petrified Han Solo-style on his journey back from Europa and left on display in Trieu's vivarium until he became relevant again, Veidt ended up theoretically "saving the world" once again by dropping a load of frozen squid on Trieu and her device in downtown Greenwood. This, of course, only happened after Dr. Manhattan managed to use Joe Keene's liquified viscera to teleport Adrian, Laurie, and Wade to Veidt's fortress in Antarctica.
Despite the fact that he only just (narratively speaking) escaped from Manhattan's unintentional prison on Europa, Veidt is back in custody. After dropping the squid, he leads Laurie and Wade to the refurbished Owlship -- more familiarly known as Archie -- that Dan Dreiberg and Rorschach left when the crash-landed on the continent in 1985. While the model was mass-reproduced for use at police stations across the country, this is the Dreiberg original. As an officer, Wade conveniently knows how to pilot it.
While Veidt was clearly prepared to live out the rest of his life at the Antarctic base, Wade and Laurie have proof -- Veidt's confessional tape to Robert Redford -- of his crimes against humanity. While he was found "Guilty! Guilty! Guilty!" by a bunch of pigs on Europa, it's yet to be determined as to whether he'll be held accountable in federal court.
For now, we can only imagine the ridiculous trip ahead of Laurie, Wade, and Adrian on their way back from Antarctica. Given his vigilante past and status, perhaps there's a chance that Veidt could end up in prison with Dan Dreiberg, the former Nite Owl II and Laurie's old flame.
