Boltz seems to have the most cautious expression of all the wolves in the Exhibit Pack.  We definitely notice his tendency to react to external stimuli and ultimately show some fear avoidance behavior to anything new, but we also see that Aidan has a lot of tolerance for Boltz when he’s anxious.  Rather than seeing that anxiety as a weakness, Aidan seems to show stronger social behavior in what appears to be reassuring to Boltz.  We do see a stronger interaction between Aidan and Boltz than we do with Aidan and Luna.
