Re: Did anyone else notice that Dr. Hamilton...(*SPOILER*)
It's unlikely that any of them are "dead", the Phantom Zone has a funny way of working. Mon-El who was on the brink of death was put into the Zone and then when he did come out it took awhile for his illness to take hold again.
Using that as an example, Hardy was the closest to dying (head first) so chances are yes, he's gone. But the rest got sucked into the Zone before any real damage could happen so Hamilton could very much so be alive.
For Hardy, if he really is going to be The Guardian like many have suggested. It's an easy fix.....The Guardian is clone...here's the reason why he was cloned. Lol
