Live Roman soldiers interacting with Indiana Jones??? Such nonsense! Yes, there were a few rambunctious phantoms in Raiders #1 & sure Sir Galahad makes a "brief" appearance in Last Crusade. But time travel? Ridiculous!
It's not like they're delaying it for re-writes, right?
DOOMCOCK WAS RIGHT!
Wouldn't it mean that Indiana Jones himself would have been erased & replaced? Such a clever move if one were to have ill intentions.
