Things are about to get downright serious in the hallways of Degrassi High.Five cast members of "Degrassi" -- Munro Chambers (Eli), Alex Steele (Tori), Cristine Prosperi (Imogen), Alicia Josipovic (Bianca) and Annie Clark (Fiona) -- sat down with HuffPost TV exclusively to give us the details on season 12. Among the tidbits the cast gave us are the introduction of a hockey team, Chaz Bono making a guest appearance as a talent show judge, and all the things you want to know about the various relationships (ahem, Clare and Eli, Drew and Bianca, Imogen and Fiona).
