Tough decision. If I let you do it, then I have to allow everyone else to do it as well. It also takes away from wrathgon's character in that his kit allowed him to do it.
As i said normally the reason you have a wild talent is your mind comes into contact with psionic energies for the 1st time and reacts. Someone that already is psionic would be born with the energies within them, even if it does not come out, you are born with the powers(IMO you can train to be a psionicist). Wild talents are a by product of psionics being used near normals. That is why my guy looks at it as a sickness cause it acts like a disease, it can be spread to others, some have good things happen, others well we dont talk about them
