Never in his years did Optimus think he would finally be able to hold you. Of course, that was the very first thing he did when he came to--no longer the massive Autobot that he used to be.

His hands were so much smaller now and you seemed just a little more bigger than you used to when he was a robot--and it made him so happy.

"Just let me hold you for a moment," his voice tells you all you need to know; let him hold you for as long as he needs.

He finally has the chance to.
