I knew about it, though I've never even seen season 5, but I did have the displeasure of watching season 4...not having a digimon partner in digimon is just wrong...I mean, biodigivolution in season 3 pissed me off to an extent, but not nearly as bad as not even having a partner to fuse with to become the digimon in the first place...*grumbles and heads off to bed*
