Aside from how I SWEAR Viv's been recycling character aspects from HH recently, Like Moxxie's crime past coming directly from Angel and now Mammon and Fizz relationship being Valentino and Angel (Which is funny, because Blitzo and Stolas is already a diet, slightly nicer version of Valentino and Angel.)
Viv is really weird about writing abuse, because Blitzo can abuse Moxxie all he wants, with one episode of him realizing that its' kinda fucked, then going right back to doing it, Loona can beat the shit out of Blitzo everyday than tell Octavia to be nicer to Stolas despite pretty much never interacting with the guy, and Stolas can be...Stolas towards Blitzo, but Stella, Valentino, and apparently Mammon are the motherfuckers who cross the line because she says so?
