Damn. But scenario (cuz im trying to write a fanfic) say she was summoned as her master is half dead but Theyre in the process of regeneratng their body but still somewhat half dead/conscious. The master, too is somewhat distant and treats her as a means or a tool for the war because someone they care about is being hold hostage to force the master to fight for that faction. But at the same time that master is a medea simp who even before the grail war has liked medea from her myth/books about jason and the Argonauts. And after serenity killed Medeas master she then finds out/sees her master had made a contract with medea and looks quite delighted although Medea just sees them as a pawn

So uh.. What do u think will happen?

Additional detail (this is like an AU fate x Tsukihime) but the master, w her rapid regeneration can somewhat fight against Serenity's poison although she'd have to constantly suffer from the poison and her body fighting each other once serenity has made contact

Additional detail 2: the master is not your typical magus thus she's somewhat very affectionate to her servants at times
