Why is Isidro at Guts and Puck's first meeting?

Why they keep making shit up that doesn't exist in the manga? I can overlook the crappy CG as long as it stays faithful to the manga, but this..
Back to the visual aspect, the hand drawn shots are very average, and don't really do Miura's artstyle justice (for example when Guts eats and even in the opening). As for the CG it's a bit better because of the shading filter they added, it looks less flat as a result. There's still "framerate" issues, and the animation which feels awkward when the characters are moving -_-
...And we're diving directly into the conviction arc WTF

No Snake Baron, no Slug count, and more importantly NO ROSINE AND NO JILL?
THOSE are my favorite parts, not friggin' conviction arc...Welp incoming Farnese wipping Guts' hard body, and riding the dragon slayer.
They better add rape horse!
