"I can know that! I am a GOD, and I am from YOUR world!" Granted, he doesn't actually know anything about Genos's life, but he can make educated guesses based on what he does know. Genos has at least two people in his personal life who support him, Saitama and the person who built him, and dear god, all the screaming fans and newspapers rushing to kiss his ass.

A little bit of the tension leaves his shoulders when Genos answers his question, something not unlike relief flooding his system. If someone did show up who would try to take his place, at least he was here first. It's a cold comfort, but he was here first. That, at least, cannot be taken from him.

"Thank you."
