Well in season one she could use them well without touching and it could at least throw Akua off for a split second.
No she couldn't.....her hallucinations were limited "as so far in terms of power as we know it" to making boys attract to her without touching for both seasons.
Even if she had to be touching It was clear that in order to cut her she had to be touched right? Well anyways she could die this way or she can somehow make it outta this...
Then she would've been cut either way.... -.-
