Obstruction Oddity

The runner cannot be put out between 3rd and home now. Heading forward, this is an easy score, we're awarding home.

Somehow, the ball is CAUGHT.

A) Runner returns and is tagged between 3rd and home on her way back (this was our actual situation).
B) Runner returns and is tagged between 2nd and 3rd on her way back.
C) Runner returns to 2nd, the ball gets away, she tries to score and is tagged out short of the plate.

Your ruling on all 3?

I'll tell you what we did after I hear some answers. The post mortem brought up sitches B and C - the umpire room was not in agreement on whether we did A right nor what the results of B or C would have been.

I've always thought the missing a base exception wasn't clear enough in the obstruction section but this seems pretty straightforward. A and B the runner is out on appeal (she's not protected from a baserunning mistake). C dead ball, award home. She is protected from being called out before she gets home. In fact, if she returns to second and stays there she's protected from being called out. Or am I mising something?

Now this is where I wish the rule was more clear: In D) she rounds third, then the catch, then she starts heading back and now she collides with F5. What do we have?
