Its one of the very few moments we have gotten to see Zodd outside of a hostile environment. And in that we also get to see that unlike a lot of apostles, or just men in berserk in general, Zodd isn't unnecessarily sexual or aggressive towards women.
I know this has been said on reddit but there's been a few panels* where I've seen zodd and he just looks, conflicted? As the dude said on reddit when you look at his facial expressions, it says a lot. He almost looks uncomfortable in my opinion. I've got a feeling he's gonna stray from griffith soon, or at some point.
To me zodd is a guy that is a true warrior and has the capability to recognise when others are true warriors with good skill, for example with guts, he respects guts because of the fact that he managed to wound zodd for the first time in 300 years. There's no way zodd isn't aware of how griffith is toying with guts and casca, so I could imagine he's going to feel conflicted naturally. I know zodd is seen as 'on griffiths side' but griffith only won zodd and his obedience a result of being defeated in a battle. I don't think zodd sees griffith as a fair fighter. I mean he isn't, not really. I feel bad for him man, poor things obviously running himself by a warrior code of some sorts like errr the dragon dude is it grunbeld (from what I've seen) And is clearly not liking what he's seeing but this code of his so to speak is getting in the way of him outright leaving.
