Sorry, I got you wrong. See

,----[ C-h v gnus-fetch-old-headers RET ]
| gnus-fetch-old-headers is a variable defined in `gnus-sum.el'.

So set it to t, if you want complete threads, or set it to 'some (that's
what I do), to get as many old articles as are needed to build a
complete sumthread.

If it's set to nil (the default) no old headers will be fetched.

So put either

  (setq gnus-fetch-old-headers t) ;; complete threads

or

  (setq gnus-fetch-old-headers 'some) ;; complete subthreads

into your ~/.gnus.el.

Bye,
