[On the Nemesis, Starscream is busy pacing when Soundwave returns]
Dr. Neo Cortex: What's wrong, Starscream?
Starscream: [growls] I have the need to be a leader. And that time will come soon. But when I do not know!
Dr. Neo Cortex: Ryvine got the same thing too. If only Megatron have got Sunset onto Makuta's side.
[Soundwave taps Starscream's shoulder]
Dr. Neo Cortex: Soundwave. You arrived. Any news at CHS?
[Soundwave brings up the video of Sci-Twi's transformation into Midnight Sparkle on his screen]
Romeo (PJ Masks): Wait, Soundwave. Show Ryan transforming.
[Soundwave shows a video of Ryan's transformation into Dark Ryan F-Freeman]
Starscream: These Dark Ryan and Midnight Sparkle may be useful to me and Ryvine.
Ryvine Sparkle: Lord Megatron could use this magic to make me a leader of the Cons.
[Starsceam and Dr. Cortex notice Megatron arriving]
Ryvine Sparkle: Lord Megatron.[bows to him] You have returned.
