He giggled, back to being excited about Halloween, “I’ve never been trick or treating before. Is it lots of fun?” Seres was in his room, probably also fluffing his hair and dawning his little labcoat. He was going to be a tiny Einstein and Magnus wanted to take all the pictures, “You look familiar. I know you’re a science guy.”

Carlos nodded, smiling at Magnus. “Yeah… it’s fun. And it’ll be great that both of us can watch Seres go around the block for the first time.

Seeing Seres, Carlos felt his throat clench – a little like when one was about to start crying. God, he was so cute! Carlos loved it. The little mustache, the hair, the coat… Personally, Carlos would have been alright with a tiny suit or a sweater like Einstein usually actually wore, but if Seres wanted to emphasize ‘scientist’ with a coat, then that was fine.
