I suspected as much. So what happens in the (very unlikely) event that a
gripper asks to see my ticket during the 30 seconds between City
Thameslink
and Farringdon? Do they carry Oyster readers? I think it's daft that I
should have to break my journey at Blackfriars or City Thameslink,
although
there is probably enough time to leap off the train at London Bridge, use
the platform validator, and then get back on - but this would carry the
risk
of losing one's seat.

It's only 30 seconds - I wouldn't bother with losing your seat.
