I'm not sure if that's just what toys/models do in this timeline, or if they're trying to indicate that he has some sort of special powers. I will note that the castle/building that he was making looks an awful lot like the place where Jeremy Irons is hanging out and the place that they showed Dr. Manhattan making on Mars.

Reiterating that there's almost 0% chance that Irons is Ozymondias. And he isn't someplace "real"/natural, if for no other reason than tomatoes don't grow on trees. Still guessing that he's on Mars, but it might not even be really happening. Like it's all inside someone's head.

Lot of other weird shit going on, like lots of talk about Dr. Manhattan being able to be different places at once.

Very good second episode. Well-acted and constructed and keeping me on my toes.
