Unrequited love sucks. IRL, fans say that Ruby loves KS and not/more than Helios, who holds the title as 'Ruby’s Husband' for gags which is so far from the truth. Maybe more believes this after Ruby stopped winning after KS was euthanized over a fractured leg.
If Uma is ever going to make a season 4 or 5, no doubt Helios will have a bittersweet ending after accepting the fact Ruby loves KS to the point she stops running
