I think about Josephine and Valerie is already pretty clear tho, one of the husband is dead nonetheless and the other one didn't care at all about anything other than court matter, so I suppose 99% they already in the MC's hands. Also about Lockhart himself, if you already have an agreement with him to not touch Elin, I also think 99% she's already in MC hands nonetheless, unless you give a wrong impression to her and make a negative points towards either love or power path which possibly gone wrong.yeah I am on Cass path already so for me Argus and Henry are already dead so hoping to claim Priscilla and especially Josephine in future updates although we are sure about Priscilla featuring in 1.0 update, I have no idea regarding Josephine and I feel next update is going to be mostly regarding Priscilla, Cass, Isis/Aurora and the rest of family members and regarding Ludwig I am not sure though as jacu_ZZ_i mentioned that they were at the ball party with Ludwig but as much as I remember those girls talking to Ludwig were just random girls who he was trying to impress in front of MC although can be wrong about this as that was long time ago.
About Arcadia's path, I think I slightly agree with n00bPanda, although there are also possibility for Alaina's path since she's also one of the court member. So chances are pretty high I suppose. Not sure about the relationship towards Alaina and the knight's guard alongside her that we saw in one of the premonition at the forest. If they're lovers, might be challenging to get her, if not 85-99% she's possible to be inside the harem.
