they literally coalesced in the most beautiful way imaginable. and i've been seeing a lot of people upset with the lack of a kiss. but, this scene should make very clear the love they hold for one another, and i actually enjoy it more without a kiss. touching forheads like this is actually a form of affection seen in the undercity, too. (cry) but what im trying to say is that their destinies are literally intertwined now forever, in every single timeline they will find each other. they were doomed to their own fates to save eachother. and jayce CHOSE to die with viktor, viktor pushed him away. he knew that this was his own end. jayce would rather die than live WITHOUT viktor. I MEAN, COME ONNNN. SOBBINGGGG. all viktor wanted was acceptance. in season 1 jayce would refer to viktors illness as a burden, and viktor in his machine form was his way of ridding himself of all his imperfections, as well as for everyone else. he wanted peace by eliminating human suffering.
