Coraline could not stop grinning at Optimus. It was the same happy, dorky smile that she usually reserved for Indiana Jones marathons, Doctor Who fans in America and Sam Witwicky. It wasn't because he was a talking, sentient, possibly alien and/or magical robot but it was because he was all of that and Sam's friend and had just saved their lives and Sam had taught them the Bro code.

"Hi Optimus Prime it's nice to meet you. Wait, you taught them the bro code?" Coraline asked looking at Sam with that smile. Coraline wrapped her arms around herself, rubbing her bare arms up and down as she looked between Optimus and Sam. "How much talking are we talking about here? What sort of talking exactly?"
