That was predictable, but Brian was really distant with Justin, who is very comprehensive (too much maybe?). That's right, there has been Ian in the past, but they were absolutely not in the same situation. Brian has been weak and he had no reason except thinking with his little head. Ian happened because they were in a very bad phase and not talking about their feelings. They were not doing it raw, they were not "in a relationship" like they are in now.
