Tony often demeaned Bobby. He kind of backed off after seeing Bobby's father and told the dad how much he appreciated Bobby looking after Uncle Junior. And in Pine Barrens, Tony even went so far to apologize for mocking Bobby's hunting outfit and thanking him for the help with Uncle Junior.

There was a scene is Season 2 where Tony ripped into Bobby about his weight. Tony pulls away in his SUV and Bobby says "take a look at yourself in the mirror" and spits on the ground in disgust.

Then once Bobby hooked up with Janice, Tony started back again on Bobby. That was more passive-aggressive tactic really aimed at Tony's disgust with Janice, so Bobby took the brunt of it.
