He does not trust people easily, but he takes silent responsibility for those he accepts as his own. Even with Guest, he observes quietly from a step back rather than acting overbearingly from the start. Once he determines they are innocent, he lowers his guard while showing a strange interest, personally visiting to speak calmly when necessary.
