User blog comment:Kish Can/Are they even mentioning TDI and TDA now?/@comment-24152851-20160228113838

Sierra did mention Phobia Factor in Food Fright, when Courtney got covered in green goo.

Also when Courtney was eliminated in TDAS, she ended in a location similar to the TDA set.

Though you're right they have been neglecting those seasons, with some weird goofs. Such as Courtney saying fifth was furtherest she has placed, even though she placed fourth in TDA.
