Law didn't like being controlled by Jesse so when he found out Jesse had a weakness he thought that he could finally have power over Jesse. He wanted Jesse to need him as much as he needed Jesse. So he decided to create an entire scenario on the Mortiat in which Jesse would need him. But when it actually happened Law got scared by the power he had over Jesse and ran away. Law chose to face his delusion of Jesse (The pure smiling one) instead of the real Jesse. Jesse forced him back to reality saying that he should face reality even if it is uncertain and scary cuz they will face it "together".
I hope this cleared up the ending for you (●'◡'●)
I have so many questions... But rn I can only ask, what the hell was this about??? Okay so lemme get this straight *inhales* Law was forced to socialize with Jesse for the sake of his parents, but along the way they kinda fell in love (?) with each other. However, Law hates that fact and doesn't want to be controlled by Jesse so when he found out Jesse's weakness, he decided to plot revenge by manipulating Jesse's subconscious so that Jesse would depend on him and he would've control over Jesse. So at the end when Jesse does succumb himself to Law, Law stopped the Moritat thingy then fast forward to the present and it's revealed that all the shit that happened was only a day after Jesse and Law met again after 5 years.
Tl;dr Law wanted to feel in control of Jesse so he trapped Jesse in a virtual reality he tampered with, and after he got what he wanted (Jesse depending solely on him) he stopped Moritat. But he's still in 'love' with Jesse so he consoles himself with the initial vr video Jesse made when they were younger...
Fuckin shit I still don't get what I just read
