The point
They both have growing up they need to do.
1. Brian should have been a bit more sensitive about the fucking situation and not been such an ass....but let's face it, he hasn't learned the importance of this skill yet.
2. Justin could have been a bit more understanding...but let's face it, he is 19, yo.
3. Brian DOES love Justin. But WE are seeing it far more than Justin does at this point...we see brian come home eagerly looking for justin, justin knows nothing about this. we see brian struggling with justin's birthday, justin sees him get him a hooker. We the viewers have a HUGE advantage over Justin at the moment.
