This is the last of this plotline, isn't it? Five seasons wondering how EZ and Angel would react when they found out Miguel is their half-brother, and the writers put this scene in as a cop out so they wouldn't have to fill the final two episodes with more filler. What a waste of time.
miguel just went there to break balls because he can’t accept the fact he’s related to the same people who FCKD his wife and killed his mother…he could also be feeling guilty about something he might do next episode…miguel saw the photos and how felipe measures his children’s height etc he saw how familial it was he just can’t accept he didn’t grow up with a proper father like his half brothers did.
