Was browsing through some episodes looking for some screenshots when it occurred to me that Christina Wells was given an established date of July 14, 1899 for her death (S2 - Reset). However, H.G. herself states that in 1893 her daughter had been gone (i.e. dead) for nearly two years - putting her death in 1891 (S3 - 3,2,1).
This is driving me bonkers at the moment. The dual dates are messing with my head and giving me too many ideas for fics.
