So, I'm rewatching the episode where the servants are having their flashbacks. And I just noticed when Sebastian asked Bard why he's always in such a hurry, there's plenty of time, and Bard explains how if he didn't hurry up in the past, he wouldn't eat. And how he just couldn't quite adjust to the peace. And well, Sebastian's face says what he wants to say and it's adorable.

It's just like this deep concerned frown and he's just staring at Bard like "I-I... Bard are you okay?"
