Assume he's still alive. Why was he not killed, where is he, and how will he factor into the story?
I feel like I'm in the minority here, but I'm convinced that Bernard is still alive. In sci-fi shows the constant rule is always that unless you see the death clearly, it didn't occur. Sims only suffocated Bernard for a few seconds, and we saw a body get torched but no face. Either he's dead and the writers want us speculating about his status (but why?), or he's alive.
Assume he's alive, assume Sims stashed him somewhere or whatever. Why did Sims keep him alive? Where is he exactly? And how will he factor into the story (in either this season or next?)
