4-3 aka the token desert chapter. Since I was using the default teams given I didn't bring any of the dragonknights and with foot units not mages or flying getting through it wasn't difficult just so damn time consuming. Guess I could say Naesala didn't feel like dodging in that chapter.
I got the scene after doing all those as well. On another playthrough I got the scene again even though I didn't bring Pelleas in the final chapter but I did have him fight Izuka though.
