Fitting that

p.501
-How fitting that this would be its last great act.

Is FITTING an adjective here? If yes, THAT sounds redundant and wrong, though I think it's because there's somthing there I can't see through./

The word 'that' is necessary. It introduces the clause that explains 'what is expected/suitable'.
