at that point phineas is already experimenting on himself a lot. mias probably scared shitless about losing another family member and having to grapple w the fact that the same death is waiting for her too. FL comes with a theory and i knew she was trying to help, shes salvaging the little hope left, but after witnessing ur uncle experiment on himself all his live to cure the family curse....the idea of someone experimenting their unfounded hypotheses on their already dying body might be a blow to an open wound for her and she was trying to get phineas comfortable for his dying days, not be a lab rat. i guess she wanted phineas to have a dignified death instead of death from a failed experiment.
i get MC's efforts, hell its natural and normal for her to still try, but i also get mia's lashing out. this whole family is just generations of unsolved griefs and peretshati was the newfound solace, but shes not a cureall.
all in all i wish that her theory is right and phineas is saved
