It's not really weird considering how the episode went.
The unspoken forgiveness toward Walt that Hank felt just before he died as Walt tried to buy his life for $80 million.
The rashness of Skylar and idiot boy when dealing with Walt. (You know the shite has obviously hit the fan and your first reaction is to, instead of figuring out what's wrong, stab Walt/call the cops).
Walt's painful, forced vindication of Skylar in front of the cops before he knows he's going to get his fresh start. Think about that. The last time he talks to his wife he essentially acts as a sociopathic (Which he is not) abuser in order to clear her name. So gut wrenching.
The only thing really unlikeable that Walt did was stab Jesse and twist the knife.
