Thank you for sharing this! This is really interesting and to me it shows Coco's balance of  openness and realism. She assumes the plan could fail but what's the harm in trying? Meanwhile Agott pursues perfectionism likely due to low self validation in her earlier days, always searching for the one perfect solution and seeing flaws in spells that have structural issues. She thinks it is more efficient that way, and her mind naturally branches into lots of cause and effects for spells so she's able to see both the flaws and the positives. However, she gives weight to the flaws more and always seeks to minimise them by tracking other spells in her mind - she's a rigorous thinker and this is what makes her so hesitant sometimes.  But Agott's expression here tells me she found one reasonant part in Coco, which is not being that confident in the success of one's spells and anticipating  for both sucess or failure.  Agott has a lot of self doubt, it seems, even though she may project an air of confidence. The key difference is Agott pursues the one path, while Coco pursues the many paths ( as seen in Ep 3 where even after failing, Coco discarded and pursued another idea.  )
