Look - when he's given Solus the benefit of the doubt in a subject before, he's learned far more than he has from being actively aggressive and combative towards the man. Even if there is some thread of genuine sympathy he's indulging, it's just good logic to hear him out.

Though he can't expect that was very high on top of his list, and his eyebrows raise quite sharply as a tinge of fear twists his insides. Which is a stupid response, he berates himself quickly; Steven is his own person who can make his own life choices and stupid mistakes with someone who reminds Tyler even more of their Keeper than Solus has managed to.

I didn't know about that. But it's more a surprised aside than any kind of bitter comment, and when he continues he's got a rather dry look on his face. I can definitely see it as a bad start to the day.
