Okay, what i'm worried about are the practicalities here. Let's say there were a scene where, I dunno, the Doctor drinks a cup of tea on the planet Zog in March 2345, and it gave him a rare case of contrafibularity flu. But in the Benny version, Jason drinks the tea, and he's the one who contracts the flu.
At the articles tea, 2345, and contrafibularity flu, how do we handle this?
