If I’m not mistaken, they were all lost in their fantasy like world. Clark dreamt about having a family on his home planet and Bruce dreamt about his father saving his family that night.
The DCAU in my honest opinion is the peak of comic book adaptations. I always prefer it over the cinematic universes. DC was untouchable from 1992 to 2006. Marvel couldn't touch DC during that time. Sure they had X-Men, EMH, and Spectacular Spider-Man but the DCAU is superior. Marvel may win when it comes to live action but DC destroys them when it comes to animation. And since I prefer animation over live action I'm more of a DC fan than Marvel. People sleep on the DCAU it's ridiculous.
