Rewatched the episode recently and it’s… well it’s certainly something. Still really confused by one thing and one thing alone though.
So Tom goes Warp 10 and became lizard. He takes Janeway who becomes lizard. They find 'em and Doc is able to revert both of them with no lasting problems at all.
So why didn’t they just Warp 10 the whole fucking ship to the Alpha Quadrant, lock out all controls via some DNA check thing to see how lizard they are, and then have Doc fix them when they got there?
