Stubbs in season 3

I thought revealing (actually just implying) that Stubbs was a host was an unnecessary add-on at the end of last season.

Though I should confess I feel the same way about Deckard being a replicant in "Blade Runner" - gratuitous and inconsistent with the story we've been shown (not to mention Scott's own decades-old waffling on the issue)

But I changed my mind this season - it's actually refreshing to see a host who's not just self-aware but completely stable. He suffers no existential crises; he's completely practical, yet still fun to watch.
