Why do you perceive him as liking her?
Their interactions have a hollowness to them on his part, like a car salesman charming a potential customer. Except instead of selling her a car, he's selling her on staying online for everyone's amusement despite that being objectively the worst advice possible for someone like her.
•She has no talent on camera.
•Her bantz are a slight step up from typical gorl comments about inceldom and penis size, but not by much
•She's already surrounded herself with literal schizos and sex offenders, purely because they stroked her ego, which everyone now knows to be the simplest attack vector.
•She will literally never live down her fucked up nudes or doing piss play or fucking carving Null of all people's name into her body. That is always going to be the preface to any introduction to her, no matter what she does from here on out
•She's genuinely mentally ill, attention seeking, materialistic, vindictive, petty, dishonest and only attractive if you squint+pinch your nose, not that I have an issue with her Jewish heritage
No, it's much easier to believe that he's being a two-faced dick instead of him literally being out of his mind. Convincing Elaine that she has a future online is for everyone's benefit, except hers.
