People have been bashing him all week for that. Without being a negative dick about it you're damned if you do and you're damned if you don't if you're Seth:
1. Cower in fear to sell that The Fiend/Wyatt is a scary threat and get bashed as being a coward and weak
2. Don't be afraid and don't sell The Fiend/Wyatt appearances and mind games as a potential terrifying threat and bury The Fiend's current work
Can't win for losing here.
