User blog comment:MoonlitShadowsoftheHumanSoul/S4: Why Bellamy Should Be Jaha's Son/@comment-24670104-20170531131110/@comment-30497461-20190804230553

Well Bellamy's dad was mentioned to be Filipino on either Twitter Or Tumbrl by Jason and Jaha isn't Filipino so 0% chance of him being his dad. Also seeing as Jaha has been dead since S5 they wouldn't do an post mortem reveal of this espsically since the 100 is nearing the end.
