This is how Soundwave studies Twilight goes in Sparkling Problems.
[We see Twilight caged up and being watched by Soundwave. Starscream comes in.]
Starscream: Princess Twilight Sparkle. Now it always comes down to just you and me.
Twilight Sparkle: Starscream. You let my friends go.
Starscream: Never. I want to know where those Sparklings that you've been hiding are.
Twilight Sparkle: Never.
Starscream: Unless you don't want anything bad to happen to your student, Starlight Glimmer.
Twilight Sparkle: They're in the Energon storage vault.
Starscream: Excellent. [to Soundwave] Soundwave, eject Laserbeak.
[Soundwave does and Laserbeak flies away to find the Sparklings]
Starscream: Good luck with your escape, princess.
[Starscream leaves and Soundwave stands guard. Soundwave then brings out his tentacles which start electrifying and moves towards Twilight with them]
Twilight Sparkle: Uh-oh.
[Soundwave electrifies her with them. Soundwave starts getting information about her. Soundwave stops and leaves to tell Starscream]
Starscream: Find those Sparklings.
Insecticon: Yes, Lord Starscream.
Starscream: What now?!
[Soundwave shows him an image of the Sparklings' location]
[Soundwave also shows him all the information about Twilight Sparkle]
