@Tinni: Apologies. I wasn't trying to theorize, just tried to draw a connection between two Hollow-related abilities in Ichigo's possession. Ended up being too wordy. I removed that portion of my post, thanks for the heads up!

The underlying point is that Ichigo is being told to use Fullbring as if it were already explained that he has the capability of doing so. Notice that he's not confused about why he would be able to use it, but rather how to do so. So, there's apparently no question that he attained those powers the same way the other Fullbringers did. My only issue is that they said they could use it since birth, whereas asides from being able to see ghosts, Ichigo has never had such power.
