While Aloy is not a traditional cowgirl, her machine-mount riding sequences with Seyka in the remastered version introduced "parallel riding" dynamics. Players noticed that if they matched Seyka’s pace exactly for the 15-minute coastal ride to the Horus site, a hidden animation played: Aloy would reach out and brush a strand of kelp from Seyka’s shoulder. This moment became legendary on TikTok under the hashtag #MarathonSapphics.
