Between this and ch 16, I feel it reinforces the idea that her Undine isn't a normal 'Undine'
Back in ch 16 Ray couldn't fight back until given permission to avenge her, and here Ador only act on the order given.
Meaning as long as Jeanie never give Undine vague enough answer for it to use its full power, it can only act like a normal Undine.
Also note that it was Jeanie who called it Undine first, unlike how Ray and Ador had to ask for a name.
