Forum:Old Wounds and Obi-Wan's flashbacks

I just wanted to ask. In "Old Wounds", when Obi-Wan is preparing to kill Darth Maul, he has flashbacks of four people, I know that Obi-Wan has flashbacks of Anakin burning up and presumably screaming,"I hate you!" to Kenobi, and one of Padme during childbirth, and one of Qui-Gon being stabbed by Maul's lightsaber, but who is the fourth flashback supposed to be, the one who gets killed by Force Lightning? I think it's supposed to be Mace Windu, since he is the only Jedi {before Revenge of the Sith} to be killed by Sidious with Force Lightning. Do you guys agree?
