Can't you just see Anakin catching Padme and Obi Wan in a genuinely innocent embrace (or maybe a lustful one--LOL):"Boohoo, ObiWan, there's something wrong with Anakin, he has a terrible temper, etc."
(LOL, maybe at that point Padme has started to figure out her hubby is mentally unstable, into black leather and S&M, etc.)
