Haizea had been ready to greet Joanna and- hm, she doesn't think she's properly met that knight yet, but the absolutely horrifying monster completely distracts her from any social niceties.

"NOPE!" she exclaims viscerally and thrusts an arm out towards the monster, stirring up a strong gust of wind aimed right at it in an almost instinctual attempt to get that thing AWAY. Probably she should have discussed strategy with the other knights first before attacking, but the sight of this mangled, eldritch CHILD is so abhorrent to her that her better judgement is limited.
