There was just one time where it was mentioned in a Patreon post that in canon, people have been demanding Sua's revival after her death, and then it was never brought up again, but I still think that's like. subtle foreshadowing
In the case that it happens, I wonder if Sua would be "revived" by the aliens and made into a robot/clone, or if Mizi will revive her through crazy methods (Imagine if Luka gets roped in because of Luka's knowledge of the ins and outs of alien stage and the nature of his birth), it would probably have more emotional relevance than that. Maybe Mizi won't be able to accomplish it (or she'll have to "kill" Sua, but that's also pushing it, isn't it). Why would she do that in the first place... I think experiencing so many major losses in one sitting could be enough to push her to the brink, if not kill her, if she doesn't push through it and continue down a brighter path, and that's where she'll go mad trying to find ways to cope, and this might be how.
Been hanging onto this art of Sua for years.. (As much as I also like to interpret this art as a metaphor for Sua's doll-like and robotic facade that the aliens only see her for, because she is a product to them) It's still so open to interpretation... so I dunno.. but I don't trust Mizi to keep her shit together in the next episode(s)
