"You vile Insect, was it you who dared to talk back to this great one?! A mere Deity?"
"Do you see anyone else here?" Enigma shrugged his shoulders and responded back, his polite facade shredded off.
Allen had literally forced him to attend lessons on how to differentiate between ally and stranger. And he had to agree, he seemed like a pushover at times.
To them, Enigma was selfless. He would be respectful to people, think about their feelings first before his, try to make them happy disregarding his feelings on the subject.
Though it was half true, Enigma just truly wanted what made them happy. In simple terms, he was fine as long as they were content and were able to sleep at night.
But Allen didn't take that excuse and thus, everyday, would spend a few hours, days at most teaching him to respect himself and care about himself more.
