on actual content rather than the incredible slapstick, 1) it seems like makima knew asking chainsaw to save her would just turn chainsaw on her, which seems counter to her stated goals from last chapter? unless getting killed was part of her plans, maybe she went back to hell or something? and 2) chainsaw/pochita seems to be trying to live out denji's dreams for him, so there's still some streak of independence/not being makima's dog in there, which maybe means the contract still isn't broken? or if it was maybe chainsaw still wants to do those things for denji?
