Now that Karyn searched in her inner being, she found how to tap her new power.
Since now it was not anymore a matter of wishes, but now of personal power, Karyn knew that she did'nt have anymore restriction about how she could use her powers. So, that meant that the restristion that made wishes unable to be COMPLTLETLY reversed(not simply changed) was not there anymore. The problem now.
To use her power, Karyn had now to tap in her own lifeforce, wich now made powerful wishes a thing not to repeat in too short lenght of time. But, as the stone had great powers, the fusion made her lifeforce now greater than probably any "human"(after all, Karyn is currently a bra, no?). But now she had two things to take care of: first, her shape. So, shaping her energy, Karyn made herself human again and, because of the place they were in now, teleported herself and Joan back to somewhere else. Wich, after this, proved that the problem of the misunderstood wishes was gone too as it was now Karyn herself that manipulated those powers now.
Then, after all this, Joan was now no more able to say something else than "Wow...".
Then, Karyn began to talk with Joan of the possibilities.
