The pages for casting guest stars list dates for 1985, 1970, 1920, and 1921.
While sometimes, when writing pages for casting actors,
the writers like to mix things up a bit to keep fans jumping, given
that the sides that have been released has someone with "big 80s hair",
looks like we really will be getting a little more time travel action
in episode 2.12.
Also, apparently in the 1920s, a Mr. Stark
wants to buy some land from a Mr. Chandler. Perhaps, given this is a
show about killer robots, maybe we'll get some cinematic references to "The
Big Sleep" as well. There certainly seems to be a mystery that is unfolding in all three time-lines. Although, it does make the future out to be a bit of a revolving door. As someone who loves time travel stories, I say bring it on.
