I will only comment on the first one, since there's a damn perception problem again.
You come of age doesn't really fit, because with that in mind I can hear a kind of stop before the k in come. So You'd come of age is better, I guess.
However, there's something that's even closer: He would come of age (this is actually what I think she says).
But I just don't understand how it is possible to hear them both, since they are so different. Even though I think "He would come of age" is the one that fits best, I can't hear the "h" at the beginning.
