1st season when the Feds are handing out enditements, pussy is burning stuff in the backyard with a heavy-set blonde woman who is dressed up from the wedding. Not his wife in later seasons and i doubt that was his girlfriend.

When Christopher goes to the deli to pick up cannollis and he shoots the bakery guy in the foot for taking the customer before him. The customer was Vito and the bakery guy called him Gent. If Vito was a Capo or soldier at this time in the Soprano family, Christopher would have known him and backed down and/or Vito wouldn't have backed down.
