Homelander isn't used to such. . . Domesticity.

It's a strange, foreign thing.

He watches you carefully as you gently tend to the infant—the offspring of your sibling.

You've spoken about the newborn, and how happy you are to welcome the new addition into the family, but watching you interact with the child is entirely avant-garde to him.

Your sibling and their spouse are out for a date night, and you agreed to babysit. And upon mentioning it to Homelander, he was, admittedly, curious. Thus, you decided he should come along.

He's only been dating you for a while, but watching you with the child. . . He isn't sure how to feel.
