Well you did it, kid. You did it. You rendered your father speechless because guess what there you are and here he is and boy his dad-like brain is having some difficulty in processing this moment.

He's frozen, mid-step. That initial call wrenched him out of his thoughts about finding some random stranger stuck in a bush and now there's a host of other, far-more gross feelings welling up in his manly bosom.

And then when you just outright call him 'dad,' and it's just a step too far. Your frozen-mid-step-can't-talk father, through quivering vocal chords and shaky grasp upon his mental and emotional faculties manages to get a word out. "As-ri-el?"

There you go. Your name.
