In "Sympathy for the Devil", David Warner's Third Doctor has been exiled by the Time Lords not to 1970 but to 1997, where he is in Hong Kong and encounters both Nicholas Courtney's Brigadier, whose career never really picked up after the Cybermen, and Mark Gatiss's Master, who's been having a fine old time for the last quarter-century. I thought this was really well done; the pairing of the Doctor and Master is balanced by the pairing of the Brigadier and UNIT's current commander (played by David Tennant!), and there were some lovely bits of dialogue.
