i think you have forgotten some details.
firstly, they did look into his brother chase, and they knew he existed.
secondly, chase didn't rewind time. the dragon already confirmed this.
(im pretty sure plants rewinded time, but this is my opinion so not confirmed)
Hold onnnnn. I was wondering when they said “he”didn’t exist in this timeline but they never looked into whether “his” brother still existed. I wonder how things will go between them now (I’m assuming he’ll try to establish a friendship but he’ll still hold his distance since their time together as siblings no longer exists). We also still don’t know who rewinded time, tho the most reasonable guess is Chase so ig it brings up the question if Chase retained his memories or not.
