Anakin meets with the Jedi head of security, Cin Drallig, who stands at the steps of the Jedi Temple. A throng of protestors -- family and friends of workers killed in the explosion -- have gathered to decry the violence of the Clone Wars, holding the Jedi responsible. Anakin shows Cin a hologram of Jackar Bowmani, hoping Drallig might have a lead.

From the protestors, Letta Turmond steps forward. She identifies herself as Jackar's wife. She's been trying to reach her husband. Anakin ushers Letta into the Temple for questioning. Letta explains that Jackar dedicated his life to the Temple. She seems desperate to find her husband.

Back in the hangar, Ahsoka studies a holographic reconstruction of the explosion. Tracing the trajectory of the blast, they find the bomb-origin point, but no residue. Russo-ISC discovers instead evidence of nano-droids -- a solid clue.

According to Jackar's personnel file, he was a munitions expert tasked with maintaining the bombs and weaponry of the Republic gunships. He had specialized knowledge of nano- technology. If he is at large, he may be planning a second strike. Russo scans through hours of security recordings, but finds no trace of Jackar anywhere else in the Temple.

Anakin and Ahsoka report back to Mace Windu. He warns them that a swift resolution to this investigation is imperative, as already there are whispers in the Senate that the military police may need to become involved.

Russo-ISC calls back Anakin and Ahsoka to the Temple hangar with a surprising development: he has found the remains of Jackar -- a severed hand recovered from the crime scene. The nano-droids were inside Bowmani's bloodstream. He was the bomb.

Anakin and Ahsoka take a turbo speeder to a street-level apartment in a rundown section of Coruscant. They head to Jackar's apartment and Ahsoka begins scanning the rooms with a handheld sensor. She finds evidence of nano-droids on food scraps in the trash -- Jackar must have ingested the explosive droids.

Just then Letta enters the apartment. She is shocked to find the Jedi there. Ahsoka's scanner finds no trace of the nano-droids on the widow, but she of course is still a suspect. The Jedi take her in for questioning, but as they leave the apartment, she makes a run for it.

Ahsoka and Anakin corner her, and when she loudly claims innocence in the death of Jackar, Anakin realizes she knows more than she's been letting on: the Jedi never told her that Jackar was dead.

When Anakin's temper starts to boil, Letta realizes she's been caught. Her attempts at misdirection have failed. She admits to feeding Jackar the bomb, but reveals nothing else. The Jedi bring her to the Temple for questioning.

At the Temple, Anakin updates Masters Windu and Yoda. Russo-ISC reports that no other nano-droids were found in the Temple, and no evidence of Jackar having accomplices have surfaced. Ahsoka is relieved that no Jedi were involved. But Mace is still concerned at how sharply public opinion has turned against the Order. The Jedi relationship with the Republic seems far more fragile than Ahsoka had imagined.
