Didn't think Flop and Taritta was going to be a thing, maybe I didn't pay enough attention to their interactions in arc 7 and 8. Was nice seeing Ram and Mizelda's talks though.
I was thinking during arc 7(?) if Rem would go with Priscilla after finishing up in Vollachia but with her now gone, the options were either back with Ram and the others or Katya. Ram being her sister and Subaru being the only person with memory of who she was makes the most sense for her going back with them but I wouldn't have been shocked if she decided to stay with Katya
