When George Michael is in the club after running into Rebel, his name is paged, and he ducks for cover, thinking it's his father. The Narrator informs us that indeed it was not his father...so who was it?
It was his father. We see Michael paging George Michael in 4x8 "Red Hairing" at 21:00.
In 4x13 "It Gets Better" at 27:00 George Michael dodges the page, assuming it was from his father. The narrator does not say it was not his father.
Unless you're speaking of another episode I'm not remembering.
