when the quadruplets started going to summer camp they realised all their names were kinda strange, so they adopted 'normie' nicknames to blend a little better. nowadays tilde's not as concerned about appearing normal as she did when she was a tween but introducing herself as tilde over pestilence invites less questions so she does generally default to that. in the horsemen sisters gc they do still call each other by their govt names though, and tilde will answer to pestilence if u decided to call her that
if you're pretty and friends with tilde there's like an 80% chance she's used your face to catfish people :3 if she offers to take pictures of u, u can safely assume it's for nefarious reasons
one hoax she's been trying to get off the ground for a while now is a cryptid of her own invention. something to rival big foot and moth man. she and [friend she's either blackmailed into this or friend who's as unhinged as she is] take turns dressing up in like a patched up bear costume with like a beak sown onto the mouth area and a big snake's tail attached to the back, while the other one takes shaky pictures in the distance. she has coined this new cryptid the bearmera (bear chimera). it hasn't exactly yielded much success but she's managed to convince a couple cryptidheads of the bearmera sightings and tricked them into to buying some of her bearmera merch.
has kind of stolen two of her neighbours' pets. the old couple next door had an outdoor cat and it got mauled by strays or possums or other such feral creatures and tilde found poor beatrice behind the apartment building one night in terrible shape. she took the kitty to the vet and then brought her back and just decided to keep her. now beatrice is tilde's new indoor cat that she's renamed ghatanothoa, and she looks absolutely gnarly. lost one eye, has a bunch of scars, and half her tail is gone, but tilde thinks she looks cuter this way actually. the other one is a hamster that belonged to the kid who lives across the hall. tilde took him when she was drunk one night and bored. she's renamed him azathoth and occasionally lets him out of his cage so that ghatanothoa can chase him around and try to eat him (dw she always gets azathoth back in his cage before ghatanothoa can actually get her claws on him)
if she likes u she will steal ur money, use u for her scams, let ghatanothoa bite u and scratch u and laugh, try to traumatise u for fun, and will just actively make ur life worse in sooooo many ways. but she's passionate! :3 protective too. will not only torture u, but also anyone who's ever wronged u<3
and incase ur curious about what her sisters are up to: warren is the frontman of a metal band and a fight breaks out in the mosh pit at every show they play (their previous vocalist died under mysterious circumstances, which ofc has nothing to do w/ war :3), bernadeth does taxidermy for fun and also just for work and collects dead bugs to display in her house, femina is a dj that's on a perpetual hunt for True Love<3 (she has left behind a trail of broken hearts n also a couple of her nastier exes have gone missing, which could mean nothing)
