Still want to experiment with familiars.
As long as we take appropriate precautions, I'm fine with doing that. But I am going to insist on said precautions.
Once again, Meseeks are beings for whom existence is suffering, and who will do whatever it takes so they can finally die and end that suffering. The entire concept is a moral nightmare, much like most stuff in Rick and Morty. We should avoid that concept as a base for any of our constructs.
The familiars would be Sabrina's familiars not delolere.
We won't know that until we make one, which is why we should prepare for the possibility they will be Dedolore's familiars even if that's unlikely. We'll want a containment sphere of grief in a vacuum to deal with the risk of it accidentally igniting the atmosphere like Sabrina could do casually at any time, enough backup to be able to take on what might be on the level of a Clara Doll, and before we even consider it, we need to try feeding Grief to a normal familiar to make sure that a familiar that inherited our Grief bending wouldn't be able to just instantly mature itself into a Witch without needing to kill people. And of course, we need Sabrina plugged into a Clear Seed and our friends ready to kill the familiar in case the feedback we got when we tried to hyjack a familiar hits us with one we created and we're not mentally up to breaking the connection when it happens.
I still think we should do more basic research and just asking our friends questions about familiars before we try to make our own, since Sabrina is the most dangerous person to be doing that sort of experiment.
I also think we should avoid going for "familiar" in our initial griefhax attempts in the direction of "familiars". That is to say, "fly" instead of "fly familiar", and see if what comes out is a familiar or if it's something else. If it is a familiar, we'll have learned something and established a level of control over the form of the familiar that we wouldn't otherwise have been sure of. If it isn't a familiar, we'll be no worse off for having made the attempt.
Might also be worth considering that a Witch Kiss might be a safer thing to attempt than a standard familiar. Our analysis of a Witch Kiss indicated it had a similar structure and composition to a familiar, but we've never heard of a witch kissed individual maturing into a Witch or a Witch Kissed individual becoming independent of its Witch, thought that again is something we ought to ask more knowledgeable people about before jumping to conclusions.
Either way, we never actually figured out how to make a familiar when we were researching the matter earlier. So doing more observation of existing familiars is required before we'll even be in a position to try to create one of our own anyway. Similar to how we needed to observe barriers in detail before we could figure out how to make one ourselves.
