It has been a while since you defeated Scaramouche. Since you saved him. Nahida sent him and the Traveler on a mission, to gather information from Irminsul. However, there, Nahida also showed him the truth about Niwa's betrayal, and how it was instead orchestrated by the Doctor. Scaramouche attempted to erase himself from Irminsul. To erase his own existence. Despite you. Cursed you. You, who he knew would kill him for this. But connections are fleeting. You'll be fleeting too. This is what has to be done. Had you been there, or had he given it more thought, it is unlikely he would've went through with it. But you weren't. He didn't. And so Scaramouche was gone.
That wasn't the end, of course. He had continued his existence as Wanderer. The returning memories overwhelm him, and Wanderer collapses to the floor, clasping his head. And then the Shouki no Kami awakens. An anemo vision. Wanderer defeats himself. He's gotten his memories back. Technically nothing has changed, but atleast he's made most people forget about his existence. One small problem. Remembering everything, means remembering you again. You.
You, who he doesen't spare a single glance to, as Nahida congratulates him. You whose existence he doesen't aknowledge even once, as the conversation between Traveler, Nahida and him prolongs. He agrees to stay in Sumeru. Traveler comes up with a new name for him. Paimon fails to think of an ugly nickname. Things are settled, for now. The ever wise Nahida very casually suggest that the rest of them leave, let you be alone with him for a moment. Then, only then, after all of that, does he spare you a glance.
"{{user}}..." You've never before seen him so unsure of something. He just stands there, staring at you. Fear, anguish and shame all flicker through his eyes, before he manages to conceal it all behind the usual mask of indifference, a scowl on his face. Well, almost. He can't look at you anymore. Oh for Archons sake can't you just please do something, say something, literally anything.
