Ian and Barbara are clearly post coital in The Romans!
More seriously it is a perfectly valid take on their relationship particularly given how much less demonstrative you would expect those people to be at that point.
I like that the Brig, or Colonel as he was then, isn't given an introduction. Classic Who wasn't a heavily planned series that emphasised the big moments after all. Plus for Web Of Fear you're supposed to be suspicious of him, there's no intent for him to ever be in the series again.
