Fiona the fox was first seen in some early comics with Tails the fox.Fiona was in love.Then they met again and maybe Fiona still liked him but not sure.Then Fiona met Sonic and they both fell deeply in love which Tails was a little bit jealous because he still liked Fionna.Later Tails kept dropping hints on Fiona (or Fi which Sonic calls her.)Then his heart was broke when Fiona dumped Sonic for Scourge (which Tails was only probably sad about that because Sonic was the only key to Fiona for Tails.Well maybe i got some stuff rong to you but this is all i know.Please no hate mail or rude comments and look me up.
