What is the "Cal thing", what has he claimed?
Think chances are high that Kiku used her ability and saved someone else from being killed. In the recent OLF round I just played there was also a role which sacrificed himself right at the first night, so I assume chances are really high that Kiku would have done the same here. And I´d rather say that after the current things happened last rounds Flower would rather spite Kiku but I don´t see Flower just killing Kiku at the very first opportunity.
