Sometimes even the smallest doubt can shake the greatest belief.Anakin and Ahsoka are abruptly called back to the Jedi Temple from the fighting on Cato Neimoidia because someone bombed the Temple, and the Jedi Council want investigators who definitely couldn't have been involved.
- Captain Crash: Chronologically the Eta-2-Actis Jedi fighters appear in this episode for the first time. Anakin manages to crash his within the first five minutes.
- Effortless Amazonian Lift: After Anakin is knocked out while piloting his starfighter and R2 has to make a crash-landing on a too-short cliff, Ahsoka leaps over to his fighter, hoists him from it, then jumps back to the cliff moments after the starfighter goes barreling off. Especially impressive considering that she could barely lift him back in the Season 1 episode "Jedi Crash".
- I Never Said It Was Poison: When ensnaring Letta with her own words, Anakin points out that no one said to her that Jackar was dead — and he's right. What Ahsoka said was, "Someone made Jackar the bomb." Unless you were tipped off that the nanodroids were in Jackar's bloodstream, that phrase would ordinarily mean that someone created a bomb for Jackar.
- Interspecies Romance: Letta, a human, was married to Jackar, an Abyssin. Although given what she did to him, it's unclear whether she really loved him or not.
- Nanomachines: The bombing at the Jedi Temple was committed using highly volatile nanodroids.
- No Body Left Behind: All that is left of Jackar is his hand.
- Shout-Out: The episode's title is a reference to Alfred Hitchcock's movie of the same title from 1936.
- Why Am I Ticking?: Post-explosion example. Jackar had millions of the aforementioned nanodroids in his bloodstream.
