Perhaps it was an inside joke because Janice is a big Rolling Stones fan (tattoo on her chest). Wasn't that right after the fight between Tony and Bobby? Tony was letting his sister know Bobby was still in his bad books. I can't remember for sure but I think Janice was also asking for money which might have been another reason Tony was peeved.
"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming
Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
