Well, we all know that Clark's powers will return gradually, and flight is always the last one to return, so he won't be effecting any rescues.

That leaves the annoying brat, Brian. But what Nan forgot to tell everyone is that Brian is currently at Dr. Klein's lab undergoing the process that will save him, but also removes his powers. So, the lad won't be able to come save the day.

Hmmmm, could be messy.

Tank (who can see a situation where Clark's invulnerability comes back enough to save him from death, but he's badly injuried... Lois is not so lucky)
