The final images show the chest that holds the Philosopher’s Stone, hooked up to some kind of apparatus while Cisco fiddles with it.
The series of 19 photos released by The CW do not show Savitar himself, nor does Wally make an appearance, although everyone else in Team Flash is shown in these scenes.
This vengeful God of Speed appeared to Wally, and from the title of next week’s episode, ‘The Wrath Of Savitar’, we know that he’s back in the spotlight.
Several of the images show Julian hooked up to the machine that allows Savitar to speak through him, in some sort of confrontation with Barry Allen.
