Hi there! Thank you so much for playing! I can't say for certain what 2013 me was trying to say there, but I think I can take a guess--
(Slight spoilers)
Probably the "little girl" there is moreso meant to say "this woman looks younger than me". The timeline in this particular game was a big plot hole HAHA 😂 (Especially Bryant's route)
I think I originally meant for Mary to be a few years younger than Elvine (thus the "little girl comment", she also happens to be on the shorter side) but then I went ahead and attempted a timeline and oops suddenly that doesn't quite make sense.
Maybe the fire took a few years off the appearance of her ghost???
You can safely chalk that line up to "plot hole" haha.
