Don't watch Trust and Betrayal first anon, please. It's a much better experience watching it after watching the first 2 seasons of the series since you watch that killer Kenshin that was hyped during the whole anime and gives you another perspective. Also TaB is one of the best anime ever and watching it first will make the series lackluster in comparison.
