There's a Traitor Among Us!

Fiona comes back to Knothole after deciding to finally ditch the evil side and join the heroes instead by first apologizing to everyone...including Sonic and Tails!That's when Fiona also decides to ask Tails out!All seems perfect especially when Knothole has a feast to celebrate a recent victory but when Sonic and Tails get poisoned is Fiona really what she says or is she lying?
