They really need to do something about that perpetual grin on Venus. Strapped down on the "altar", preparing to be solar-fried, she looked as though she were loving every minute of it!
By the diameter of that solar ray that struck the Earth, it should have done a heck of a lot more damage than just destroy a few ships out on the field.
Zoonie was able to read Venus' thoughts and figure out that she was in that temple, but how was he able to lead Steve straight to the secret entrance, some distance away? I had the impression that she had been knocked out when captured, but perhaps not.
