Update: The clip appears to have been taken down. The light's not winning today.
"A Parable of Grief and Mourning" topped Matt Zoller Seitz's list of "7 Things That True Detective Was About." It's a point that came into focus at the very end of the season — specifically its final scene — when Rust talks about feeling his dead kid's presence. It's a theme that's echoed in this deleted scene, in which Rust and Lori fight over his "philosophies" that prevent him from having kids with her. This is at the root of their eventual breakup. Well, this and the fact that Rust is probably a real drag to be around after a while.
