Niles ends up marrying C.C. in the finale, so when Fran and Maxwell finally get together, Niles is not left out of the happy ending. He gets his own romantic payoff at the same time, and the show closes with him moving into a new life with C.C.

What happens to him

  • Niles has been teasing a long-running romance with C.C. throughout the series, and it finally pays off in the last episode.
  • In the finale, C.C. accepts his proposal, and they get married while Fran is giving birth.
  • After that, Niles and C.C. leave the Sheffield household and start their own life together.

In plain terms

Fran and Maxwell’s marriage does not sideline Niles; it actually happens alongside his own big relationship ending. The show uses that ending to give both couples a satisfying conclusion.

TL;DR: Niles marries C.C. in the finale, so he gets his own happy ending right when Fran and Maxwell reunite and officially settle down.
