Original Commentary

This, mind you, is the comic showing how Brisbane and Brent interact with each other, which is why Sofia doesn't have much to say. In all honesty, I pictured this comic's build-up as something like the courthouse scene in Ghostbusters 2. Except that in this case, the emotional outburst ends with a bite instead of with the Scoleri brothers - Terrence

Modern Commentary
He's not an attack brant. You can't really train them to guard things. However, if you talk sternly at Sofia, then Brent is probably going to do something about it.

If you talk sternly at Brent, he's probably going to ignore you.

But man, can't Sofia make a token effort to keep the peace? - Terrence
