The Jedi continue their investigation in Ord Mantell City . Along with Windu are Obi - Wan Kenobi , Tiplee , and Aayla Secura . They discover a Death Watch helmet , confirming their intelligence that Mandalore had allied with Darth Maul .

On the outpost , Maul contacts Darth Sidious via hologram and informs him that Dooku and Grievous have been captured .
