tbh I don't see Guts going berserk because if he did, in his rampage he'd damage the ship and it would sink and everyone would drown which would be the shittiest way the manga can end. Unless Farnese brings him back before he does too much damage? But there is a lag, and without Schierke to guide her she has no idea what to do, so unlikely. He's probably still catatonic and is just letting himself be lead by the Kushan because what's the point anymore. Or plot twist, he actually knows Kushan and had a nice chat and knows they're tight with Rickert.
did the artist change or smth it looks slightly off, not bad per say but just off. went back to previous chapter never mind what I said it makes sense since our god is gone and we shall never be forgiven for outliving him
