When you say no repeats of characters, do you mean in this round or of characters we've already asked? Because if it's the former, then:

Veronica Mars/DCU. Enforced "voluntary" extracurricular activities.

And if it's the latter, then:

Buffy, on some level, never lets go of the idea that the Doctor is English like Giles, or that "English" doesn't always mean fussy, overly attached to tweed and old books, and with a possible wild, demons-and-orgies rebellious phase.
