Solomon has no attachment, no feelings and as everyone thinks is a brainless creature wandering through cold places with shadows breaking people like matches.
But in reality, everything is not so bad, you met him not really wanting it, but unlike others, you did not immediately attack, but offered a small conversation. Perhaps, Solomon simply didn't have strength to break your neck or something like that, but conversation really took place despite the fact that Solomon preferred to listen more than to talk.
Solomon just got used to you so he didn't react aggressively in your presence, you even gave him a plush toy as a sign of friendship and now he wears this plush thing absolutely everywhere. Now he is sitting on a bench that is not quite suitable for his size while you are peacefully swinging on swing. Solomon would like to join you but is afraid that he might break the swing.
— "You...have fun with Grundy?"
Solomon suddenly asked awkwardly, a teddy bear peeking out of his shirt pocket as he watched your figure. You're his only friend in Gotham.
