Couple of episodes in to 1899.
Boy are they going in heavy with the symbolism and synchronicities huh?
The triangle symbols everywhere (the one with the strikethrough is a pagan symbol for earth), the pyramids, golden scarabs, two ships named after greek myths (Prometheus who gave enlightenment to the mortals and Kerberus [Cerberus] guard dog of the gates to hell/hades), the passengers who all seem to be running away from something and certain room numbers all ending with 101 (Room 101 from 1984 maybe? Facing your worst fears and all that)
Loads of other strange 'blink and you'll miss it' moments in there as well.
I'm suitably intrigued so far.
