tabby is brought up again in the true ending! you can get it by hiding under the bed when in enides room :3
Oh cool, thanks for telling me!
I feel like in most endings the plot should be good (and you can do that while hiding reveals for other endings) so having a major character hidden under a bed is eh.
Also, Tabby being killed (? just because it's a past lover doesn't mean she's dead) is kinda thrown in there with no lead up, points for surprising me I guess.
