I saw an ask about how many of the trolls would survive - to the part about Feferi not being able to beat the Condesce, didn't she have Gl'bgolyb loyal to her (Feferi) instead of the Condesce due to Condy going so far away? would that possibly give Feferi any sort of advantage? (wow that sounds confusing sorry)

Only if they fought in the water of Alternia, but even then Condy might still be able to win
