Miraak is finally free from Apocrypha and is also overconfident in his ability to face anyone who stands in his way. He walks through Solstheim alone until he meets Neloth. Miraak says something that gets Neloth pissed off and they start fighting. The last dragonborn never reached Solstheim so he won't be interfering. Miraak is overconfident in his skills and abilities so he meets Neloth alone with no cultist, seekers, or dragons on his side.Lets assume Miraak's bend still won't work on Neloth.. Will Neloth the Telvanni master wizard take this or would the betrayer a.k.a first Dragonborn take this?

Scenario 2 - Neloth is replaced with Fyr instead.

Neloth has a quote in the game that says how Miraak would had been as his apprentice, this shows Neloth could talk bad but he could back those words up?

Neloth would wipe the floor with Miraak and even the player character.

i'd imagine miraak would win, without bend will or herma-mora's blessing (whatever the reason) he could take the last dragonborn down with a twitch of his hand. Granted neloth is a badass, just can't see him standing against a dragonborn, especially a master like miraak
