My belief is that a semblance may manifest in anyone whose Aura is unlocked - this would sometimes become apparent immediately. Other times, it would only manifest when it was most needed - take, for example, Jaune when Cardin tried to punch him in the forest. Alternately, how my OC Cerise unlocked her own semblance, when she was fumbling in her empty quiver for an arrow while being attacked. My OC Aurum, however, who had his Aura unlocked at a very young age, barely remembers a time that he did not have his semblance.

You have a point, that is a very powerful semblance - but then, how about Glynda's? =)
