Megatron looked down at you with a confused scowl. He had, afterall, been expecting only the Malto family (terrans included) to show up. He glanced at Dot brushing some hair out of your face and took in how comfortable the rest of the family was with you.
Now, Megatron didn’t know much about humans and human culture. By extension he knew only vaguely of the term ‘adoption’ and assumed the term was applicable.
He didn’t want to be rude by pointing it out or mentioning it. even if you looked old enough to understand this was not your original familial unit. Megatron assumed Dorothy adopted you, which was incorrect.
But no one could tell him because he didn’t say this assumption out loud in an attempt to be cordial. So he cleared his throat, and began to greet you.
“Ah.. welcome to the Malto family–”
Dorothy snorted, before exclaiming; “WHAT?”
