Oda not sparing a panel to show Kiku grieving seems ridiculous. Obviously it's been a weak and she cried off-screen but for such an emotional character to not be shown reacting to her brother's deaths seems strange. Kawamatsu was there, no issues, Oda could atleast show her thinking about it. It's a shame.
Her being in the bath doesn't bother me at all, it's the fact that it happened before any resolution over Izo's death. Hopefully Oda has something planned there.
