I looked at Johns wikia
John’s relationship with Vriska is a very complex one. At first, Vriska decided to help John on his quest as a means of competing with Terezi, who was helping Dave. Vriska was very bossy and a control freak towards John at first, which he found kind of annoying, but he still enjoyed talking with her. Vriska and John’s feelings developed deeper: John used more of her typing quirk to please her, Vriska made an outfit for John that she said makes him totally hot, and John showed her Nicolas Cage, who became her fangirl crush. However, after Vriska killed Tavros, Vriska opened up more of her feelings than she had with anybody else. She held John’s opinion of her in highest respect, fearing that he would be angry with her. She has told him about not only her remorse for killing, but how her views of killing compared to those of troll society, how much she admired humans for being weaker but nicer, and her entire background. Though he was a bit freaked out after hearing that Vriska had murdered twice and killed thousands to feed her Lusus, he did not think any less of her after receiving the shock.
What happened to that.
