When Obi-Wan Kenobi meets Osi Sobeck for the first time face to face he says to him: "I must say, you're not at all what I pictured. Someone with such a soft voice." This is probably an inside joke referencing the voice actor James Arnold Taylor. He voices Obi-Wan Kenobi in the show with a soft, soothing voice. In the Citadel story arc he additionally voices Osi Sobeck with a relatively harsh, raspy voice.
The 'Jedi fortune cookie' message that opens the show reads "Anything that can go wrong will."
