This is a pretty bad show six episodes in. The first episode is the only one where the script doesn't totally sink the whole proceedings. Episode six was, as usual, dumb as shit. So, they were just teleporting away instead of dying? Ok, so where is the teleport graphic? We've seen it, and it's completely visually distinctive from the death animation, and is not present at all during either of the "deaths". This is like the most elementary fuckup in telling a mystery story - making the mystery impossible to solve because the writer cheated to hide information from you, in this case, the fact that they were escaping with teleports.
