“It’s Always Sunny in Philadelphia”

(9 p.m., 9:31 p.m., 1:02 a.m., FXX): Season 13 concludes with “Mac Finds His Pride,” which picks up a story thread that has been unspooling since last season: Mac’s (Rob McElhenney) coming out as an openly gay man. As Pride Day approaches, Frank (Danny DeVito) tries to recruit Mac to ride on the gang’s parade float. In the process, he comes to realize Mac never will be truly comfortable in his sexual identity until he comes out to his father, Luther (guest star Gregory Scott Cummins).
