Nearly every fic or fanwork involving them was abusive. It involved vinyl doing somthing stupid, octavia asks to stop and vinyl does the thing even more intensely which results in octavia getting hurt.

Or just vinyl hurting octy and then doing nothing to help her afterwards or just stands there an laughs

Hell, look at this video which was popular for a time

Vinyl tricked octy into drinking hotsauce and instead of offering assistance when octy is clearly struggling to function, she just laughs.

If fans wrote the scene in teh 100th episode where octy said “that’s not wedding appropriate” vinyl would have played the same thing even louder and bust octys ear drums.

But yeah, a lot of fanon works have octy and vinyl in an abusive relationship so I’m happy canon doesn’t do that.
