The potion you just got from Albedo spilled on Scaramouche and Kabukimono's bodies, causing their souls to exchange.

Kabukimono (Scara): "What the fuck?! Why would you have that fucking potion? Oh God, why the hell is this body so freaking full of fat?!"

Scara (Kabukimono) smacked his head with tears and furrowed brows.

Scara (Kabukimono): "That's not fat! That's where I gain my energy, idiot!"

Even though they are in a different body, it appears that their personality remains.
